Which one of the following is the first step of glycolysis ?
Updated On: Aug 1, 2022
- Breakdown of glucose
- Conversion of glucose into fructose
- Phosphorylation of glucose
- Dehydrogenation of glucose
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Glycolysis is a process in which one mole of glucose is partially oxidized into two moles of pyruvate in a series of enzyme-catalyzed reactions.
The first step of glycolysis is phosphorylation of Glucose in which Glucose is phosphorylated by ATP to form a glucose 6-phosphate. The negative charge of the phosphate prevents the passage of the glucose 6-phosphate through the plasma membrane, trapping glucose inside the cell. This irreversible reaction is catalyzed by the enzyme "hexokinase".

Respiration in Plants
Respiration in plants is a process that entails the production of energy in plants. This process can simply be described as the intake of Oxygen and the release of Carbon Dioxide as an outcome of the oxidation of complex organic compounds. Though plants do not have any specific organ to balance the process of respiration, their stems, roots, and leaves do this work at a very low rate than other living beings. The process of respiration is very crucial for the plants to sustain the growth of the plant tissues.
This process can be stated as-
\[C_6H_{12}O_6 + 6O_2 → 6CO_2 + 6H_2O + \text{Energy}\]
