BIOENERGETICS
Total Questions:
Bioenergetics
- Definition: Bioenergetics is the branch of biology that explores how living organisms acquire, transform, and utilize energy.
- Energy Currency: Adenosine triphosphate (ATP) is the primary energy currency in biological systems, facilitating energy transfer within cells.
- ATP Structure: ATP consists of adenine, a ribose sugar, and three phosphate groups linked by high-energy bonds.
- ATP Hydrolysis: The hydrolysis of ATP releases energy by breaking the terminal phosphate bond, forming adenosine diphosphate (ADP) and inorganic phosphate (Pi).
- ATP Synthesis: ATP is synthesized through processes like oxidative phosphorylation in cellular respiration and photophosphorylation in photosynthesis, where energy from electron transport chains drives ATP production.
- Energy Transformation: Organisms obtain energy from nutrients like carbohydrates, fats, and proteins, which is then transformed into ATP through metabolic pathways such as glycolysis, the Krebs cycle, and oxidative phosphorylation.
- Cellular Respiration: Cellular respiration is the metabolic process in which cells break down organic molecules, such as glucose, to produce ATP, carbon dioxide, and water, releasing energy in the form of ATP.
- Photosynthesis: Photosynthesis is the biochemical process by which autotrophic organisms, such as plants, algae, and some bacteria, convert light energy into chemical energy stored in glucose, releasing oxygen as a byproduct.
- Importance: Bioenergetics is vital for all living organisms, providing the energy required for cellular activities, growth, development, reproduction, and maintenance of life processes.
