how might differences in enzyme concentrations affect rates of photosynthesis and respiration?

Answers

Answer:

enzymes are biological catalysts which speed up the rate of biochemical reactions

Increasing the concentration of enzymes would speed up the rate of photosynthesis and respiration due to the fact that the enzyme substrate complex can occur on a much larger scale i.e. more enzymes would be able to bind with more substrates producing more Oxygen in the case of photosynthesis and more ATP in respiration

Decreasing the concentration of enzymes would have the opposite effects

The differences in enzyme concentrations affect rates of photosynthesis and respiration are process accelerators.

What enzymes are involved in photosynthesis?

Enzymes such as Rubisco, sedoheptulose-1,7-bisphosphatase, aldolase and transketolase dominate the control of photosynthesis. Reductive fixation of CO2 requires ATP and NADPH and their concentrations in the stroma increase when chloroplasts are illuminated.

The chemical reactions involved in photosynthesis are controlled by enzymes . The temperature increases the number of collisions increases, therefore the rate of photosynthesis increases. However, at high temperatures, enzymes are denatured and this will decrease the rate of photosynthesis.

Explanation:

The body is supported by its skeletal structure. It gives the body form, motion, and shape while safeguarding delicate organs. The body is supported by its skeletal structure.

What is skeletal system?

The main structural component of your body is the skeletal system. It is made up of bones and connective tissue, such as ligaments, tendons, and cartilage.

Vertebrates are creatures with a spinal column or backbone, including humans. They are supported by a strong internal framework that is built around a noticeable spine.

Our bodies' living bones use oxygen and release waste products throughout metabolism. They have functional tissues that require nutrients, blood flow, and the ability to remodel or change shape in response to changes in mechanical stress.

The skeleton, which is made up of bones, acts as a rigid framework to support and shield the body's soft organs.

Therefore, The body is supported by its skeletal structure. It gives the body form, motion, and shape while safeguarding delicate organs. The body is supported by its skeletal structure.

gene regulation can occur only during transcription and translation.

Answers

The statement described is false, gene regulation is a process that can occur at any time during the expression of a gene.

Gene regulation includes all those processes that affect the action of the final products of genes, that is, the regulation of the synthesis of macromolecules is called gene regulation or expression.

This regulation can be carried out at any stage of the synthesis or maturation of the macromolecules, and taking into account many variables it will be developed at the most appropriate point.

One of the most important regulation points is carried out at the level of transcription, since this is the initial stage of transfer of genetic information, control is achieved at the beginning.

Therefore, we can conclude that the pathway that leads from DNA to proteins is made up of multiple stages, and gene regulation can occur at any time during them.

Explanation:

hydrolysis is the reverse of dehydration because it breaks a covenant bond by adding a water molecule

hope this was helpful ☆☆

In translation, the dehydration synthesis reaction is catalyzed by DNA polymerase enzyme. Therefore, the correct option is B.

What is DNA polymerase?

DNA polymerases are a group of enzymes that are responsible for catalyzing the synthesis of DNA. Their main function is to replicate the DNA. These enzymes work in pairs and a responsible for replicating two strands of DNA  in a tandem. DNA polymerases α and δ are primarily responsible for nuclear DNA replication. There are at least 15 DNA polymerases known to exist in humans.

Translation is the process by which the genetic code carried by mRNA is decoded to produce a specific sequence of amino acids that will form a protein. This process involves the ribosome, which is responsible for assembling the protein chain by joining amino acids in a specific order dictated by the mRNA sequence. Therefore, the correct option is B.

Answers

Answer: Higher infant mortality rates cause higher fertility rates.

Explanation:

Countries with high infant mortality rates are usually countries where families rely on children to help out the family. High infant mortality rates and a need for children means that those people will continue to try to have children until they have some that survive. If more children die, and people need to have more children, there will be a higher fertility rate.
