ATP and Energy Metabolism

ATP (Adenosine Triphosphate) is the primary energy currency of the cell, providing energy for various cellular processes.
ATP is composed of adenine, a five-carbon sugar (ribose), and three phosphate groups.

ATP-ADP Cycle and Energy Transfer

ATP plays a crucial role in linking exergonic (energy-releasing) and endergonic (energy-requiring) reactions, allowing energy to be transferred between them.
During exergonic reactions, ATP is generated, and during endergonic reactions, ATP is broken down to ADP (Adenosine Diphosphate).

ADP and Energy Metabolism

ADP is the primary recipient of energy from the breakdown of ATP, allowing it to be recycled back into ATP.
The primary role of ADP is to accept energy from the breakdown of ATP, which can then be used to drive endergonic reactions.

Cellular Respiration and Energy Production

The primary source of energy used by living organisms is the breakdown of glucose and other nutrients through cellular respiration.
Cellular respiration is the process by which organisms use oxygen to turn fuel into chemical energy, producing ATP as a byproduct.

Types of Respiration and Energy Production

Anaerobic respiration is a type of respiration that can break down sugars to generate energy in the absence of oxygen.
The energy required for endergonic reactions is called activation energy.

ATP Synthesis and Phosphorylation

The process of combining ADP with a phosphate molecule to make ATP is called phosphorylation.
The energy released from breaking a molecular bond in ATP comes from the energy stored in the phosphate bonds.
ATP provides the premier energy molecule in living cells, powering various cellular processes.

This quiz module covers the learning competencies related to explaining coupled reaction processes and describing the ATP-ADP cycle in the context of general biology.
