Lecture 3

Question 1

Describe how oxidative phosphorylation is connected to the citric acid cycle

Answer 1

The citric acid cycle generates a net worth of 6NADH2 molecule and 2 FADH2 molecules and they act as electron carriers that enter oxadative phosrphorylation to produce ATP

Question 2

Describe, in basic terms, how ATP is generated by oxidation phosphorylation

Answer 2

Protons are pumped out of the matrix into the intermmebrane space by 4 protein complexes. The protein will then follow the concentration gradient into the matrix but the only awaible options are the ATP/ADP translocase and as the protons pass it will catalyze the reaction that forms ADP to ATP.

Question 3

· Name the main components of the respiratory chain, and where they are located

Answer 3

There are the four protein complexes and the ATP synthase complex

Question 4

· Describe the basic structure and function of mitochondria

Answer 4

The mitochondria has the inner matrix, an intermembrane space, and and inter and outer membrane. The function of the mimtochondria is to produce ATP.

Question 5

· Know the energy exchange ratio for NADH and FADH

Answer 5

6NADH2 molecule and 2 FADH2 is generated from the citric acid cycle. NADH2 genrates two H+ and FADH2 also generates 2H+

Question 6

· Describe the main purposes of the pentose phosphate pathway, an where it occurs

Answer 6

The purpose of the pentose phostphate is to generate ribose-5-phstphate which is needed for nucleotides synthesis. It takes place in plants.

Question 7

· Describe the basic structure and function of mitochondria

Answer 7

The mitochondria has the inner matrix, an intermembrane space, and and inter and outer membrane. The function of the mimtochondria is to produce ATP.
