Krebs Cycle

Question 1

What is the first step of the kerbs cycle

Answer 1

The 2 carbon molecules combined with the oxecycotate and release coenzyme a and forms citrate

Question 2

What happens in the second stage of the kerbs cycle

Answer 2

The citrate loses a carbon dioxide to form a 5 carbon molecules

Question 3

What happens in the thrid stage of the kerbs cycle

Answer 3

The 5 carbon molecule releases a co2 and bad forms reduced nad by accepting hydrogen it then form 4 carbon molecule

Question 4

What happens in the fourth stage of the kerbs cycle

Answer 4

The carbon 4 molecule consecutive hydrogens are removed to reduce nad to nadh2x and then fad is reduced to fadh then atp is also synthesis through substrate level phosphorylation

Question 5

What happens in the last stage

Answer 5

The remaining 4 oxecycoate combine with the 2 carbon molecule

Question 6

What are coenzymes

Answer 6

They are molecules that enzymes require in order to function and play a major role in photosynthesis and reapiration it carries h from one molecule to another

Question 7

What does kerbs cycle do to large molecules

Answer 7

Breaks them down into smaller molecules

Question 8

What does it do to the produced hydrogen

Answer 8

It is carried by the nad to the electron transfer chain and provides energy for oxidative phosphorylation

Question 9

What does the regenerated 4 carbon molecule do

Answer 9

It combined with acetylcoenzyme a
