Respiration

Question 1

What are the waste product (s) of

anaerobic respiration in yeast?

Answer 1

Ethanol and CO2

Question 2

What must a cell do under anaerobic
conditions to allow glycolysis to
proceed?

Answer 2

Recycle NADH to NAD+

Question 3

At the end of glycolysis and in the
presence of oxygen, pyruvate is
converted to:

Answer 3

Acetyl coenzyme A

Question 4

In the Krebs cycle, most of the
energy released by the oxidative
breakdown of glucose is conserved as:

Answer 4

ATP, NADH and FADH2

Question 5

At which step in the Krebs cycle is

FADH2 generated?

Answer 5

Step 6

Question 6

What is the name of the enzyme that

catalyses step 6 in the Krebs cycle?

Answer 6

Succinate Dehydrogenase

Question 7

Which of the following is NOT
essential to generate the proton motive
force for ATP synthesis?

Answer 7

A permeable inner membrane

Question 8

Theoretically, how many ATP
molecules can be synthesized from a
single molecule of glucose?

Answer 8

30 or 32

Question 9

The use of which transport system
ensures that the maximum number of
32 ATP molecules can be generated
from 1 molecule of glucose?

Answer 9

The malate-aspartate shuttle

Question 10

The Malate - a ketoglutarate
transporter is an integral component of
the Malate-Aspartate shuttle that
transports reducing power in the form
of NADH from the inter-membrane
space in the mitochondrion across the
inner mitochondrial membrane into the
mitochondrial matrix. What type of
membrane transporter is it?

Answer 10

Antiport
