Respiration (7.3)

Question 1

Balanced symbol equation for respiration

Answer 1

6O2 + C6H12O6 ———> 6CO2 + 6H2O + (38) ATP

Question 2

In respiration there are two ways ATP can be produced via phosphorylation: substrate level and oxidative

Answer 2

SUBSTRATE - involves the phosphorylation of ADP to ATP without the involvement of the mitochondrial ETC and ATP synthase

OXIDATIVE - generation of ATP via the breakdown of glucose and other fuels

Question 3

Give the adaptations of the mitochondria for enabling respiration

Answer 3

Mitochondria have a double membrane structure, with an inner layer with many folds to create a high surface area. This provides more space for more metabolising proteins and therefor they are able to create more energy at one time. They also have a small amount of mitochondrial DNA, allowing them to create mitochondrial proteins quicker than from nucleic genes.
