ANSWERS
In the combined processes of glycolysis and cellular respiration, what is
consumed and what is produced?
Glucose is consumed, and carbon dioxide is produced.
Which of the following describes the process of glycolysis?
It represents the first stage in the chemical oxidation of glucose by a cell.
A glucose molecule is completely broken down to carbon dioxide and water in
glycolysis and the citric acid cycle, but together these two processes yield only a
few molecules of ATP. What happened to most of the energy that the cell obtains
from the oxidation of glucose?
It is stored in NADH and FADH2
Which statement about the citric acid cycle is correct?
The last reaction in the citric acid cycle produces a product that is a substrate for the
first reaction of the citric acid cycle.
The electrons stripped from glucose in cellular respiration end up in which
compound?
water
Which of the following statements about the chemiosmotic synthesis of ATP is
correct?
The chemiosmotic synthesis of ATP requires that the electron transport in the inner
mitochondrial membrane be coupled to proton transport across the same membrane.
Which one of the following statements about the redox reactions of the electron
transport chain is correct?
The redox reactions of the electron transport chain are directly coupled to the
movement of protons across a membrane.
In the absence of oxygen, what is the net gain of ATP for each glucose molecule
that enters glycolysis?
