Question

multiple choice question
which of the following is released from atp, providing a cell with energy?
adp and p
a phosphate group (p)
water
glucose
adp only

Explanation:

Step1: Recall ATP hydrolysis reaction

ATP (adenosine triphosphate) undergoes hydrolysis. The reaction is \(ATP + H_2O
ightarrow ADP+P_i+\text{energy}\). When ATP provides energy to the cell, it breaks a phosphate - bond.

Step2: Analyze each option

• ADP only: ATP hydrolysis gives both ADP and a phosphate group (\(P\)), not just ADP.
• Glucose: Glucose is not a product of ATP hydrolysis. ATP is an energy - carrier molecule in cells, and glucose is a sugar molecule used for energy production through processes like cellular respiration.
• Water: Water is a reactant in ATP hydrolysis (\(ATP + H_2O

ightarrow ADP + P_i+\text{energy}\)), not a product released for energy.

• A phosphate group (\(P\)): While a phosphate group is released, the full products are ADP and \(P\).
• ADP and \(P\): According to the ATP hydrolysis reaction \(ATP

ightarrow ADP + P+\text{energy}\), when ATP provides energy, it is converted to ADP (adenosine diphosphate) and a phosphate group (\(P\)).

Answer:

ADP and \(P\)
