Respiration

Question 1

Process of the links reaction?

Answer 1

• pyruvate is actively transported into the mitochondria matrix
• pyruvate + NAD + coenzyme A = acetal coenzyme A + reduced NAD + carbon dioxide

Question 2

Process of the kreb’s cycle?

Answer 2

• acetyl coA combines to a 4C molecule =6C molecule
• 6C loses carbon dioxide x2 and hydrogen
• it gives electrons and protons to the Electron transport chain
  ( during this, reduced FAD and reduced NAD and ATP is produced)

Question 3

The process of the electron transport chain

.

Answer 3

• electrons from glycolysis and kreb’s passed to an acceptor
• passed along chain of carriers, by oxidation, reduction reactions
• electrons lose energy as passed along chain
• energy used to combine ADP+Pi to make ATP
• at the end of the chain the electrons combine with protons to oxygen to make water

Question 4

Process of glycolysis?

Answer 4

-glucose is converts to phosphorylated glucose
- glucose phosphorase concerts phosphorylated glucose to 2x triose phosphate
- triose phosphate is converted to pyruvate, phosphofructokinase aids this
( during this, 2x ATP is made and 2x reduced NAD is made)
