Which of the following statements about cell respiration is true?
A In the electron transport chain, Oz is converted to CO2.
B Glycolysis splits sugar to produce pyruvate and FADH2-
C Electrons leave the electron transport chain in a molecule of water (H20).
D
Both B and C are correct.

Answers

Answer 1

The statement which is true about cell respiration is; Choice B: Glycolysis splits sugar to produce pyruvate and FADH2-

Definition of terms:

Cellular respiration is a process used by all living organisms to convert glucose into energy.

Cellular respiration is a collection of three unique metabolic pathways: glycolysis, pyruvate oxidation, the citric acid cycle, and the electron transport chain.

Glycolysis; This pathway is anaerobic and takes place in the cytoplasm of the cell.

This pathway breaks down 1 glucose molecule and produces 2 pyruvate molecule. A process which releases FADH2- in the process.

Pyruvate Oxidation: In eukaryotic cells, the mitochondria is the site of pyruvate oxidation. The release of CO2 is a characteristic of this step.

The Electron transport chain: The electron transport chain is the final component of aerobic respiration and is the only portion of glucose metabolism that uses atmospheric oxygen.

Electrons are rapidly transferred from one component to the next to the endpoint of the chain, where the electrons reduce molecular oxygen, O2 producing water in the process.

What regulates breathing rate and how does the body sense when to breath?

Answers

Answer:

Involuntary respiration is controlled by the respiratory centers of the upper brainstem (sometimes termed the lower brain, along with the cerebellum). This region of the brain controls many involuntary and metabolic functions besides the respiratory system, including certain aspects of cardiovascular function and involuntary muscle movements (in the cerebellum).

Explanation:

The respiratory centers contain chemoreceptors that detect pH levels in the blood and send signals to the respiratory centers of the brain to adjust the ventilation rate to change acidity by increasing or decreasing the removal of carbon dioxide (since carbon dioxide is linked to higher levels of hydrogen ions in blood).

Answer:

A

Explanation:

Modern cell theory states: cells are the basic unit of structure and function for all living things, all cells come from preexisting cells, and all living things are made from cells. It does not state that all living things are multicellular, in fact there are plenty of unicellular organisms. Therefore the answer is A.

How does cooling of magma affect crystal size?

A) Slow cooling creates small crystals

B) Fast cooling creates both large and small crystals.

C) Slow cooling creates large crystals

D) Fast cooling create large crystals

Answers

Answer:

When magma cools, crystals form because the solution is super-saturated with respect to some minerals. If the magma cools quickly, the crystals do not have much time to form, so they are very small. If the magma cools slowly, then the crystals have enough time to grow and become large.

Answer:

I learned about this, Uhm...

C is the right answer bc igneous rocks cool and form crystals.

Lava, since it comes out of a volcano, cools faster and has smaller crystals since they could not be developed enough.

Magma, still underground, cools slower than lava because of all the density and heat, which causes bigger crystals.

Hope this helps :)

state two features of diffusion that do no apply to active transport​

Answers

diffusion moves ions from high concentration to low using no metabolic energy and active transport uses metabolic energy in the form of atp to move ions from high concentration to low concentration

What does active transport require that diffusion does not? Passive mechanisms like diffusion use no energy, while active transport requires energy to get done.

What two features distinguish active transport from diffusion? An example of diffusion is oxygen moving from the airways to the lungs - there is very little oxygen in the lungs but lots in the air. Active transport is the movement of particles from an area of low concentration to an area of high concentration. This process requires energy (ATP)

What are the 2 key features of active transport? There are two types of active transport: primary active transport that uses adenosine triphosphate (ATP), and secondary active transport that uses an electrochemical gradient. An example of active transport in human physiology is the uptake of glucose in the intestines.
Both use ion channels to move ions across the cell membrane, in or out of the cell. Differences: Passive Transport (or Diffusion) moves ions from high concentration to low, using no metabolic energy. Active Transport moves ions from low concentration to high, using metabolic energy in the form of ATP.

Macromolecules are polymers containing long chains of molecular sub-units known as monomers. These play an important role in biophysical processes and composed of thousands of atoms that are covalently bonded.

Carbohydrate is a biomolecule having carbon, hydrogen and oxygen atom.It is the main source of energy of the body.

Lipids are macromolecules that are insoluble in water and the main function is to serve as structural component of cell membrane.

Proteins are macromolecules that are extremely complex in structure and made up of amino acid residues joined by peptide bonds.

The average molecular weight of proteins encoded in the human genome is about 50,000. A few proteins are very much larger than this average. For example, the protein called titin, which is made by muscle cells, has a molecular weight of 3,000,000. Estimate how long it will take a muscle cell to translate an mRNA coding for an average protein and one coding for titin. The average molecular mass of amino acids is about 110 daltons. Assume that the translation rate is two amino acids per second.

Answers

Answer:

13,636 seconds = 227.3 minutes = 3.79 hours

Explanation:

The titin protein has a molecular weight of 3,000,000 daltons, while the average molecular mass of one amino acid is 110 daltons, so it is expected that this protein is composed of 27,273 amino acids (3,000,000 daltons/110 daltons = 27,272.72). Moreover, and since the translation rate is two amino acids per sec, it is expected that the protein will be synthesized in approximately 3.79 hours (27,272.72/2 = 13,636 seconds = 227.3 minutes = 3.79 hours).
