Respiration In Plants Mock Tests

In the glycolysis pathway, glucose is broken down into two molecules of pyruvate. During this process, the net gain of ATP molecules is:

How many ATP molecules are consumed during the preparatory phase of glycolysis per glucose molecule?

The total net ATP yield from one molecule of glucose during complete aerobic respiration (glycolysis + Krebs cycle + ETC) is approximately:

How many ATP molecules are net produced during glycolysis from one molecule of glucose?

Krebs cycle (citric acid cycle) occurs in which part of the mitochondrion?

The respiratory quotient (RQ) is defined as the ratio of:

The electron transport chain (ETS) in the inner mitochondrial membrane pumps protons (H⁺) into the intermembrane space. Which of the following is the correct sequence of electron carriers in the ETS?

The TCA cycle (Krebs cycle) takes place in which part of the mitochondrion?
