during steps 7 and 10 of glycolysis, atp is generated. what type(s) of reactions occur to generate atp from adp and the substrate?

hydrolysis
dehydration
isomerization
phosphorylation

Explanation:

Identify the mechanism of ATP generation in steps 7 and 10 of glycolysis

In glycolysis, steps 7 and 10 involve the transfer of a high-energy phosphate group from a phosphorylated substrate directly to ADP, forming ATP. This specific biochemical mechanism is known as substrate-level phosphorylation.

Evaluate the given options against the mechanism

• Hydrolysis: Involves breaking bonds using water, which is not the primary reaction generating ATP here.
• Dehydration: Involves the removal of water, which occurs in step 9 (catalyzed by enolase) but not the ATP-generating steps.
• Isomerization: Involves structural rearrangement, which occurs in steps 2 and 5.
• Phosphorylation: Specifically, ADP is phosphorylated to ATP by receiving a phosphate group. Therefore, phosphorylation is the correct reaction type.

Answer:

• Hydrolysis
• Dehydration
• Isomerization
• Phosphorylation (Correct answer)
