cell respiration

Acetyl Co-A

• is formed from the breakdown of pyruvate

• enters the Kreb cycle

• combines with a four carbon compound

• all of the above

Water is an end product in

• lactic acid fermentation

• alcoholic fermentation

• krebs cycle

• electron transport chain

for each molecule of glucose that is broken down during aerobic respiration, the Krebs cycle produces

• 2 ATP

• 4 ATP

• 6 ATP

• 8 ATP

glycolisis and aerobic respiration are different in that

• glycolisis occurs on the cell membrane, while aerobic respiration occurs in mitochondria

• glycolisis occurs only in photosynthesis, while aerobic respiration ins part of cellular respiration

• glycolisis occurs in the absence of oxygen, while aerobic respiration requires oxygen

When coenzyme A bonds to the decarboxylated pyruvic acid what molecule is produced

• NADH

• NAD

• acetyl-coA

How many carbon dioxide are produced in the Krebs cycle for every glucose molecule

• 4

• 2

• 6

How many of each of the NADH is made in Krebs cycle of every glucose molecule that undergoes cellular respiration

• 4 Carbon dioxide

• 4 ATP

• 6 NADH

How many ATP are produced for each glucose molecule in Krebs cycle

• 2

• 4

• 6
