Q

TRUE or FALSE: Overall ATP yield: 2ATP, 2NADH, 2 Pyruvate

A

TRUE

17
Q

glycolysis occurs under aerobic or anaerobic conditions?

A

anaerobic

18
Q

does glycolysis occur in faster rates in tumours? if so, what does this result in?

A

yes, it results in anaerobic metabolism because capillaries can’t provide enough aeration for tumours at the rate they grow.

19
Q

aerobic fate of pyruvate is… which then goes into the TCA cycle

A

Acetyl CoA

20
Q

oxidation of glucose by glycolysis occurs in which part of the cell?

A

cytoplasm

21
Q

how is NADH replenished when not enough oxygen to support aerobic oxidation of pyruvate?

A

NADH is synthesised via the reduction of pyruvate to lactate

22
Q

anaerobic fate of pyruvate is ??? and ???

A

ethanol production and lactate production

23
Q

can humans use the ethanol production pathway in the anaerobic fate of pyruvate? What are we missing?

A

no, humans don’t have pyruvate decarboxylase or alcohol dehydrogenase

24
Q

the two step reduction of pyruvate to ethanol is reversible or irreversible?

A

irreversible

25
Q

Lactate formed by ??? (or by
erythrocytes) can be recycled.

A

active skeletal muscle

26
Q

pyruvate to lactate pathway involves the enzyme…?

A

lactate dehydrogenase
