Lecture 11 Fermentation and DNA structure

Question 1

Fermentation is not equal to anaerobic respiration because….

Answer 1

does not completely break down macromolecule to CO2/H2O

Question 2

Fermentation still starts with…

Answer 2

glycolysis, stops after glycolysis because of no O2

Question 3

2 Problems with Fermentation

Answer 3

pyruvate is toxic
once all NAD+ is reduced to NADH, glycolysis stops

Question 4

In muscles, pyruvate is reduced to…

Answer 4

Lactate

Question 5

reduction of pyruvate…

Answer 5

uses electrons from NADH to recycle to NAD+ for use in glycolysis

Question 6

In yeast, pyruvate is reduced to…

Answer 6

ethanol ( more toxic us )

Question 7

is glycolysis sufficient for anaerobic ATP production?

Answer 7

Yes because while it only produces 2 ATP, it is very fast, The ETC produces a lot of ATP but is very slow and is limited by O2 delivery

Question 8

Muscles can do fermentation when…

Answer 8

You use a short burst of energy or are using high energy over a long period of time to give extra energy.

Question 9

Criteria for genetic material?

Answer 9

1. Information
2. Replication
3. transmission
4. variation

Question 10

Alternative fuels are

Answer 10

protein, fats, carbs
