Study Notes
Electron Transfer and Energy
- Electron transfer during cellular processes involves the molecule NAD+.
- The process of changing energy from one form to another is known as energy conversion.
Organisms and Food Production
- Autotrophic organisms, such as plants, can produce their own food through photosynthesis.
Decomposers and Food Webs
- Decomposers are responsible for digesting dead organic matter in a food web.
Energy Flow and Electron Carriers
- Energy flow in living systems is referred to as energy metabolism.
- The electron carrier NAD+ has a reduced form, NADH.
- FAD (Flavin Adenine Dinucleotide), derived from vitamin B2, is an electron carrier.
- FADH2 is the reduced form of FAD, and its oxidized form is FAD.
Energy Release and ATP
- Exergonic reactions release energy.
- The process of ATP being used in a reaction and a phosphate group being temporarily attached to a substrate is called phosphorylation.
- ATP allows the cell to briefly store and transport energy within the cell.
- The main role of ATP in the cell is to provide energy for various cellular processes.
NAD and Anabolic Reactions
- NAD stands for Nicotinamide Adenine Dinucleotide.
- NAD plays an important role in anabolic reactions, such as fatty acid synthesis, and in photosynthesis.
