FAD & NAD

Question 1

Intro

Answer 1

FAD and NAD are coenzymes that plays a critical role in aerobic respiration

Question 2

What they do

Answer 2

1. They accept H(e and p) released i different stages of respiration
2. They transfer these to the electron transport chain in the inner membrane ( site of oxidative phosphorylation) , the site where H are released from coenzymes

Question 3

overview of steps

Answer 3

H^+ and e- are important in the electron transport chain as they play a role in the synthesis of ATP

1. E is released to electron transport chain
2. H + is release when e is lost
3. electron transport chain drives proton to move up the concentration gradient from inner membrane to inter-membrane
4. This establish a proton gradient. Proton moves down the concentration gradient by facilitated diffusion from inter-membrane to matrix, this releases the energy needed to drive ATP synthase to synthesis ATP
