Explanation:
transport proteins in the cell membrane play an important role in cell transport by
Answer: Membrane transport proteins are specific and selective for the molecules they move, and they often use energy to catalyze passage. Also, these proteins transport some nutrients against the concentration gradient, which requires additional energy.
Explanation:
Membrane transport proteins play a crucial role in the movement of solutes across biological membranes, including ions, nutrients, neurotransmitters, and a wide range of medications.
What function do transport proteins provide in living membranes?
The cell membrane contains transport proteins that enable the selective transit of particular molecules from the surrounding environment. Each transport protein recognizes a certain chemical only (indicated by matching colors)
The two main kinds of membrane transport proteins are carrier proteins and channel proteins. The specific solute to be transported is bound by carrier proteins (also known as carriers, permeases, or transporters), which then go through a series of conformational changes to move the bound solute across the membrane.

Which is false?
A) fatty acids can enter Krebs cycle through a process called beta-oxidation
B) ATP can inhibit the enzyme phosphofructokinase
C) Too much NADH can inhibit pyruvate decarboxylase
D) DNA is often broken down to enter Krebs Cycle
Answer:
D) DNA is often broken down to enter Krebs Cycle
Explanation:
A) is true. Beta-oxidation is a process whereby fatty acids serves as precursor for cellular respiration. It is the catabolism (metabolic breakdown) of fatty acids into ACETYL coA, NADH and FADH2 molecules, which enters the Kreb's cycle to continue the process of cellular respiration.
B) is true. Phosphofructokinase is an enzyme that catalyses the conversion of fructose-6-phosphate to fructose-1,6-bisphosphate in glycolysis. However, phosphofructokinase enzyme has been shown to be allosterically inhibited by ATP and citrate by reducing its ability to bind to its substrate (fructose-6-phosphate).
C) is true. Pyruvate dehydrogenase is a complex of enzymes that catalyzes the oxidation of pyruvate into ACETYL coA. This oxidation of pyruvate produces C02, acetyl coA and NADH molecules. Hence, the Pyruvate dehydrogenase complex can be inhibited by its own product (NADH) if produced in excessive amount.
D) is false because Deoxyribose nucleic acid (DNA) is never broken down to enter the Kreb's cycle. DNA is a nucleic acid strictly for the storage of genetic information in a cell. It has no business with cellular respiration.

what is the meaning of photosynthesis
Answer:
Photosynthesis is the process by which plants and other things make food.It is an endothermic (takes in heat) process.Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy.
Explanation:(what happens in this process)
-Sunlight energy is converted into chemical energy by using chlorophyll.Gives plants their green color to the plants.
- Chlorophyll absorbs red and blue light and uses the energy to convert water and carbon dioxide into glucose.
- Plants convert sugar and energy from water, air and sunlight into energy to grow
- formula for photosynthesis : 6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy
-formation of carbohydrates from carbon dioxide and a source of hydrogen in the chlorophyll-containing cells (as of green plants) exposed to light.
- Plants, algae, and a group of bacteria called cyanobacteria are the only organisms capable of performing photosynthesis .
- plants breath in carbon dioxide and breath out oxygen.

Check out the list of scientific names . These names all represent animals. These are all animals but they cannot reproduce to produce fertile offspring with each other. What conclusion can be drawn from the last statement?
Answer:
I think this is the list right? - Felis catus Sylvilagus audubonii Parus inornatus Euarctos americanus
Explanation:
When two members of the same species (male and female) mate, they produce fertile offspring.
The conclusion that can be drawn from this is that due to the fact that from looking at the scientific names of the animals, there are different genus and species names, there would be no interbreeding between them as they do not belong to the same species.
And if peradventure there is crossbreeding, the union would be unable to produce fertile offspring.
Answer:
None of the animals are the same species.

increases the lethality of T-cells.
eliminates all lymphocytes that have been built that would bind and kill healthy, unaffected body cells.
Answer:
The correct answer is - eliminates all lymphocytes that have been built that would bind and kill healthy, unaffected body cells.
Explanation:
Self-testing in the immune system is a very important step as it helps in analyzing if the immune cells or lymphocytes. To fight against the intruders, the immune system should initially recognize them. That is, the immune system must have the option to recognize what is nonself (remote) based on what is self. The immune system can make this identification since all cells have distinguishing recognition molecules (antigens) on their surface.
Self-test helps in identifying and eliminate in all lymphocytes that have built and attack the healthy cells and killing them.
During exercise, sensory receptors detect changes in oxygen and carbon dioxide levels in the blood. This information is then sent to the brain's medulla, which causes the heart to beat faster and increases the rate of breathing. Exercising also causes the nervous system to signal the pancreas and thyroid gland to release hormones which regulate metabolism. Which statement is best demonstrated by this scenario? A. Hormones act as signal molecules between all body systems. B. Exercise is important for the body to function properly. C. Nerves transmit and respond to every major system in the body. D. Increased heart rate and blood flow decrease oxygen supply.
A. Hormones act as signal molecules between all body systems
Peripheral Chemoreceptors (Carotid + Aortic Bodies) and Central Chemoreceptors in the Medulla Oblongata detect high Carbon Dioxide levels in the blood during exercise. The respiratory centre in the Medulla Oblongata + PONS stimulate the intercostal muscles and the diphragm to contract in order to increase the rate and depth of breathing as to decrease levels of Carbon dioxide in the blood.

Why do developed countries have lower growth rates than less-developed countries? higher birth rates lower death rates higher death rates lower birth rates
The correct answer is D. Lower birth rates
Explanation:
The growth rate is determined by how fast the population of a country or a zone increases. This factor is higher in developing countries than in developed countries. One factor that contributes to this is the low birth rate in developed countries as people have fewer children in these countries, and therefore there are fewer births per year than in developing countries. This is influenced by the accessibility to contraceptive methods, higher education levels, and cultural values. Also, fewer births mean the population will grow slowly, and therefore the growth rate is lower.
Answer:
lower birth rates

Based on your understanding of the process of photosynthesis, what are the strengths and weaknesses of this model?
Answer:
photosynthesis is the process of making food by plant in presence of sunlight and chlorophyll in necessary condition is called photosynthesis .
i think its strength are,
1. it converts the light energy, co2and water inthe form of glucose.
2. it manufactures oxygen during this process.
some weakness are,
1. if there is no sunlight then this process cannot be performed.
2. it may take a long time to do this process.
hope it helps uh..
Answer:
The model’s strength is that it clearly shows that the process is quite complicated and that it takes place in different parts of the chloroplasts. It also shows most of the major molecules produced. But it doesn’t show the major steps of the Calvin cycle, so that’s a weakness of the model. It also doesn’t clearly show the process of the electron transport chain.

The size of the stem increases in the width due to the ........... meristem.
Answer:
Intercalary
Explanation:
There are three types of meristems : apical, lateral and intercalary.
These are found at different parts of the plant, but their ultimate job is to multiply and so increase the length of the plant.
The length of the stem is determined by the apical meristem, which is found at the tip of the plant.Of this meristem múltiples, the plant grows taller.
The root of the meristem is determined by the lateral meristem, which is found at the bottom of the plant, near the roots.
The thickness of the plant is determined by the intercalary meristem, which is found at the centre of the plant, and when they multiple, the plant increases in width.
Hope this helps.
Good Luck.
