In stage 1 of glycolysis which 2 reactions use ATP
|
|
fructose-1, 6-bisphosphate
|
|
|
glucose
|
|
|
Glucose-6-phosphate
|
|
|
Glucose
|
Explanation:
Detailed explanation-1: -In the first step of glycolysis, the glucose ring is phosphorylated. Phosphorylation is the process of adding a phosphate group to a molecule derived from ATP. As a result, at this point in glycolysis, 1 molecule of ATP has been consumed.
Detailed explanation-2: -The first step in glycolysis (Figure 9.1. 1) is catalyzed by hexokinase, an enzyme with broad specificity that catalyzes the phosphorylation of six-carbon sugars. Hexokinase phosphorylates glucose using ATP as the source of the phosphate, producing glucose-6-phosphate, a more reactive form of glucose.
