Question

which process is responsible for conformational changes that facilitates active transport? atp hydrolysis lipolysis phosphorylation

Explanation:

To determine the process for conformational changes in active transport:

• ATP hydrolysis: Provides energy but doesn’t directly cause conformational changes in transporters.
• Lipolysis: Breaks down lipids (fats) and is unrelated to membrane transport.
• Phosphorylation: When a phosphate group (from ATP hydrolysis) is added to a transport protein, it triggers conformational changes, enabling active transport (e.g., in the sodium - potassium pump).

Answer:

phosphorylation
