Expert Solution

Substrate-level phosphorylation

Substrate-level phosphorylation is a process in which a phosphate group is transferred from a phosphorylated donor which is rich in energy to ADP to synthesize ATP.

Oxidative phosphorylation

Oxidative phosphorylation is the process by which ATP is produced by the transfer of electrons from NADH or FADH2 to oxygen O2 with the support of electron carriers.

Cellular respiration

In Cellular respiration the glucose molecules are oxidised through a controlled metabolic pathway including the different stages such as Glycolysis, pyruvate oxidation, citric acid cycle and oxidative phosphorylation in which energy is produced. This energy is utilised to production of ATP.

Four components of cellular respiration

The four components are described below

1.Glycolysis – Glucose goes in and ATP is produced

2.Pyruvate Oxidation – Pyruvate goes in and NADH is produced

3.Citric acid cycle – Acetyl CoA goes in and CO2 is produced with ATP and NADH

4.Oxidative Phosphorylation – NADH and FADH2 goes in to produce ATP
