Question

Evce Monobran.UUUU 4. Phosphofructokinase is the rate-limiting enzyme that controls the rate on decreases its activity upon binding ATP. ATP concentrations mus y upon binding ATP. ATP concentrations must be relatively high for this to happen. This type of control of a biochemical pathway is called There are other ways to control the rate of biochemical pathways w ntrol the rate of biochemical pathways within cells. List three other typical ways cells would control rates of biochemical pathways. of relatie prapor 5. A gradient of protons drives the ATP synthase of mitochondria. In what specie mitochondrial compartment is the [H+] highest? 6. During aerobic cellular respiration, 2/3 of the CO2 produced come from _?- a. production of lactic acid from pyruvate b. production of Acetyl Coenzyme A c. steps in the Krebs cycle d. transfer of protons to the electron transfer system All of the water produced during aerobic cellular respiration comes from ? a. the recombination of protons and electrons in the Krebs cycle b. the dehydration reaction in glycolysis c. the electron transport system d. the oxidation of inorganic phosphate during ATP formation by the synthase The movement of pyruvic acid into the mitochondria is favored when ? a. the cell's oxygen content is high b. the mitochondrial NADH is high c. the cytosol oxygen content is low b. the cytosol pH is low

Answer 1

.4. a) that biochemical pathway is called as glycolytic pathway.

• b) 1,6 bhasphate is rate limiting step in glycogenesis
• isocitrate dehydrosinase catalyzes the oxidation reaction which is rate limiting step in TCA cycle.
• in cell signaling pathway dehydration of CDK1 on Y15 is the rate limiting step of signaling pathway of mitosis.
