Match the following with the options given in below.
a. Glucose serves as the initial reactant.
b. Involves the creation of high energy electron carriers and CO2 from the substrate molecule.
c. Occurs in the cytosol of a cell.
d. Produces the most ATP.
e. Involves the use of oxygen to pick up excess hydrogen and electrons.
Options:
1. Glycolysis
2. Electron transport chain
3.Citric acid (Krebs) cycle

1. Glycolysis - Option- A, C

2. Electron transport chain -Option-D, E

3.Citric acid (Krebs) cycle- Option-B

Explanation:

1.Glycolysis

Glycolysis is the first phase of the cellular respiration which oxidizes the glucose molecule to pyruvate molecules in ten enzymes catalyzed reaction. The reaction takes place in the cytosol of the cell.

2. Electron transport chain

The last phase of the cellular respiration where the electrons flow or transports through the electron carriers and in last is picked or accepted by the oxygen. The process forms about 24 molecules of ATP through ATP synthesis.

3. Citric acid (Krebs) cycle

The third phase of respiration which forms the reducing equivalents like NADH and FADH₂. The process produces 4 molecules of Carbon dioxide.
