anaerobic respiration

Question 1

alcohol fermentation

Answer 1

conversion of pyruvate to CO2 and ethanol

Question 2

lactic acid fermentation

Answer 2

production of lactic acid

Question 3

what is the role of obligate anaerobe

Answer 3

to convert ATP to NADH to keep glycolysis going

Question 4

what do endospores survive

Answer 4

long exposure to air and O2

Question 5

tell the difference between fast and slow twitch fibres

Answer 5

Slow :
contract and fatigue more slowly
long distance runners have more 
contain more myoglobin and ATPase
more mitochondria 
more succinct DH enzyme
cannot increase through exercise 

Fast:
sprinters
contain more lactase dehydrogenase to produce ATP fats 
can increase through exercise 
fewer mitochondria 
fast glycolytic

Question 6

what is gluconeogenesis

Answer 6

synthesis of glucose from non carbohydrate precursor

so, from pyruvate

Question 7

where most of the potential energy remains

Answer 7

in the bonds of fermented products

Question 8

what is the products of Yeats metabolism

Answer 8

2 ATP, 2 H2O, 2 CO2, 2 Ethanol

Question 9

what is the final products of lactic acid fermentation

Answer 9

2 lactase, 2 ATP and 2 waters

Question 10

how vegetative cells are killed

Answer 10

by exposure to oxygen but there endospores are able to survive

Question 11

what can form lactic acid

Answer 11

muscle cytosol and some bacteria
