Question

Which of the following statements is not true? Glycolysis produces most of the ATP required by aerobic organisms like us Glycolysis produces pyruvate, which is consumed by the Krebs cycle Glycolysis occurs in the cytosol of the cell Glycolysis is the first stage of cellular respiration • The Krebs cycle reactions Takes place in the cytoplasm Converts glucose to pyruvate Generate ATP with the help of an enzyme complex called ATP synthase Yield ATP, NADH, and FADH2 • Which of the following is essential for oxidative phosphorylation? Rubisco NADH Carbon dioxide Chlorophyll • Oxidative phosphorylation • Produces less ATP than glycolysis Produce simple sugars • Depends on the activity of the ATP synthase Is part of the photosystem I electron transport chain

Answer 1

Question 1) Incorrect statement is- 'Glycolysis produces most of the ATP required by aerobic organisms like us.'

Glycolysis produces only 2 ATP molecules. Kreb cycle produces 36 ATP.

Question 2) Generate ATP with the help of enzyme complex called ATP synthase

ATP synthase is a enzyme complex with different sub units (F0 and F1)which helps produce ATP via aerobic respiration.

Question 3) NADH

NADH is an electron carrier and transfer their electron to generate ATP.

Question 4) Oxidative phosphorylation is a part of photosystem I electron transport chain

ATP generation requires phosphorylation of ADP. This is caused by phosphorylation of substrates in the pathway leading to generation of proton gradient driving ATP synthesis.
