List the events that takes place during oxidative respiration.

Explain why the energy value of lipid is twice that of carbohydrate [2]

What is meant by respiratory quotient (RQ)?

State the respiratory substrate for each of the given RQ

Dahlia plants store a compound called inulin , which is a polymer of fructose. The structure of fructose is shown in the diagram. Calculate the RQ when inulin is hydrolysed and then respired aerobically

Q3. The ATP synthesised in respiration can be used to make larger and more complex biological molecules from smaller molecules.

Name the type of reaction that occurs when larger more complex biological molecules are made from smaller molecules.

b. The first part of glycolysis uses ATP. Explain why ATP is needed in the first part of glycolysis [2]

c. State the precise locations of substrate-linked phosphorylation reactions in aerobic respiration [1]

d. Explain what happens to pyruvate in the link reaction in aerobic respiration [2]

a. ATP is synthesised from ADP and Pi in a phosphorylation reaction. State the two different ways in which this phosphorylation reaction occurs in aerobic respiration [2]

b. Coenzymes are important in all four stages of aerobic respiration. Describe and explain the role of the coenzymes NAD and FAD in aerobic respiration.
