glycolysis

Question 1

what is aerobic respiration

Answer 1

oxygen and glucose produces water, a lot of atp and carbon dioxide

Question 2

what happens in the cytoplasm what is added to glucose and why

Answer 2

2 phosphates from hydrolysis of two molecules of atp are added to to the diffused in glucose to form hexose biphosphate to make it more reactive so it can split to form triosephosphate with a lower activation energy

Question 3

what happens to the triosephosphate

Answer 3

oxidation of the molecule 2 hydrogens are removed and taken up by the hydrogen carrier nad to form reduce nad

Question 4

what happens to the oxidaate triose phosphate

Answer 4

through reactions 2 phosphate molecules are removed from each triosephosphate to form pyruvate

Question 5

what is net produce

Answer 5

TWO MOLECULES OF ATP, TWO MOLECULES OF REDUCED NAD, TWO MOLECULES OF PYRUVATE

Question 6

how does aerobic and anaerobic now differ after glycolysis

Answer 6

then aerobic continues into the link reaction with the addition of oxygn, however anaerobic stops here and produce lactate or ethanol.

Question 7

what does glycolysis suggest about first organism

Answer 7

that we have evolved life before just existed with co2 which took place in glycolysis , this pyruvate can then be converted into ethanol or lactate

Question 8

what happens to the pyrvate

Answer 8

it takes part in link reaction in the mitochondria

Question 9

what does the pyruvate combine with in the mitochondria to form what

Answer 9

it oxidises completely to form acetate and release co2 and hydrogen the hydrogen is taken up by nad to form reduced nad

Question 10

what does the acetate combine with

Answer 10

the coenzyme a to form acetylecoenzyme a which is used in the krebs cycle
