which of the following consitions would slow down the rate of atp formation in mitochondria?

a. an excess of nadh

b. deficiency of inorganic phosphate

c. a high concentration of oxygen?

d. a high concentration of atp?

i have no idea but i believe it is NOT C

2.electrons from NADH that is formed during glycolysis are passed down to the electron transport chain by?

a.using a specific transporter to move nadh into mito matrix

b. transferring electrond to carnitine

c transferring electrons to oxaloacetate to form malate n then move to matrix

d directly donating electrons from NADH to coenzyme q

i think this answer is D

Answer #1

1.

ATP formation.

ATP is formed from ADP and inorganic phosphate. This conversion required some amount of energy. This energy is from oxidation of NADH.

So, the excess of NADH and oxygen produces excess amount of energy so, that excess of ATP.

a. an excess of nadh: Increase the formation of ATP

b. deficiency of inorganic phosphate: phosphate is reactant, so deficiency of phosphate slow down the rate formationof ATP

c. a high concentration of oxygen? : Giving higher amount of energy, so that increase the rate.

d. a high concentration of atp?: Increase product concentration, decrease the rate.

Correct options: (b) and( d).

FOR ATP ACCOUNTING QUESTIONS, ASSUME THAT "cytosolic NADH" (NADH produced in glycolysis) ENTERS MITOCHONDRIA WITHOUT USE OF ENERGY -- and therefore without lowering the eventual ATP yield. That is, assume that the malate-aspartate shuttle is used to move cytosolic NADH into mitochondria. Phosphorolysis produces glucose-1-phosphate. Calculate the yield of ATP equivalents from complete aerobic catabolism of glucose-1-phosphate. A. 3 B. 8 C. 30 D. 31 E. 32 F. 33
