Respiration

Question 1

How much energy is released from atp to adp

Answer 1

30.5kj/mol

Question 2

Glycolysis

Answer 2

Two phosphates are added onto glucose from atp
Hexose bisphosphate is split into 2 triose
Phosphate
Triose phosphate is oxidised to pyruvate which coverts 4ADP to ATP and reduces 2NAD to 2NADH

Question 3

Link reaction

Answer 3

Pyruvate is converted into acetyl coA
Loss of a carbon forms CO2
More NAD is reduced

Question 4

Kerbs cycle

Answer 4

Citrate looses a carbon, reduces NAD, and releases a CO2 to form a 5 carbon compound
5 carbon compound repeats this process to form 4 carbon compound
4 carbon compound releases ATP
Then reduces FAD and NAD to form oxaloacetate

Question 5

Oxidative phosphorylation

Answer 5

The formation of ATP by oxidising reduced NAD and FAD in the presence of oxygen and the proteins of the electron transport chain

Question 6

How is reduced NAD used for oxidative phosphorylation

Answer 6

It releases its hydrogens which are split into protons and electrons

Question 7

What is the relevance of oxygen in oxidative phosphorylation

Answer 7

It is the final electron acceptor and combines with electrons and protons to form water
