NEET2023BotanyRespiration in PlantsActual
Given below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): ATP is used at two steps in glycolysis. Reason (R): First ATP is used in converting glucose into glucose-6-phosphate and second ATP is used in conversion of Fructose-6-phosphate to Fructose-1,6-diphosphate. In the light of the above statements, choose the correct answer from the options given below
Options
- AA is false but R is true.
- BBoth A and R are true and R is the correct explanation of A.
- CBoth A and R are true but R is NOT the correct explanation of A.
- DA is true but R is false
Correct answer
B. Both A and R are true and R is the correct explanation of A.
Step-by-step solution
Glycolysis is a multi-step, enzymatic process which is common for both aerobic and anaerobic respirations. This takes place in the cytoplasm of the cell. There are as many as 10 steps in glycolysis and overall, 2 ATP molecules are used for one molecule of glucose. First ATP is utilised when Glucose is phosphorylated to give rise to glucose-6-phosphate by the activity of the enzyme hexokinase and second in the conversion of fructose 6-phosphate to fructose 1, 6-bisphosphate.
