Bio: Chapter 4 Review Part 2

The correct order of the stages of cellular respiration is

• electron transport - Krebs cycle - glycolysis

• glycolysis - Krebs cycle - electron transport.

• Krebs cycle - glycolysis - electron transport

• glycolysis - electron transport - Krebs cycle.

For each glucose molecule that starts glycolysis, the Krebs cycle occurs

• once

• twice

• three times

The products of glycolysis include

• two pyruvates

• two ATPs

• two NADHs

The electron transport chain of cellular respiration is located in

• the thylakoid membrane of the chloroplast

• the matrix of the mitochondria

• the mitochondria inner membrane

• the chloroplast stroma

How many NADH are produced with each turn of the Krebs cycle?

• 2

• 4

• 8

• 10

The final electron acceptor of cellular respiration is

• water

• oxygen

• hydrogen

The earliest life forms probably produced ATP through

• cellular respiration

• photosynthesis and cellular respiration

• glycolysis only

The two electron carriers of cellular respiration are

• NADH and NADPH

• NADH and FAD₂

• NADH and FADH₂

• NADPH and FADH₂

The Krebs cycle is also known as

• the citric acid cycle.

• chemiosmosis

• the Calvin cycle

The most ATP molecules that can be made from one glucose molecule is

• 2

• 4

• 38

• 83
