Which type of reactions are driven by the energy provided by ATP?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3: Endergonic Reactions.
Explanation:
- In biology and chemistry, endergonic reactions are those that require energy from an external source to proceed.
- The Role of ATP: ATP (Adenosine Triphosphate) is referred to as the cell's 'energy currency.' When a cell needs to perform a task that consumes energy (such as protein synthesis or muscle contraction), it utilizes the energy released from the breakdown of ATP.
- Energy Coupling: The hydrolysis of ATP is an exergonic process that releases energy. This released energy is used to 'drive' or power endergonic reactions, which otherwise would not occur spontaneously.
Types of Reactions (Quick Revision):
- Endergonic: Reactions that absorb energy (driven by ATP).
- Exergonic: Reactions that release energy (e.g., cellular respiration).
- Redox Reactions (Option 2): Reactions in which oxidation and reduction occur simultaneously.
