Study Notes
Metabolism and Redox Overview
- Phosphoglycerokinase is an enzyme responsible for phosphorylating phosphoglycerol.
- The phosphorylation process utilizes ATP, converting it to ADP in the reaction.
Oxidation and Reduction Concepts
- Oxidation occurs when a molecule loses one or more electrons, resulting in a higher oxidation state.
- Reduction refers to the gain of electrons by a molecule, lowering its oxidation state.
Key Molecules in Redox Reactions
- NADH is a reduced form of nicotinamide adenine dinucleotide (NAD+), carrying high-energy electrons.
- In redox reactions, NADH serves as an important electron donor, contrasting with oxidized NAD+.
Energy Comparison
- When comparing energy states, NADH possesses higher energy compared to NAD+ after it transfers electrons to NADH oxidase.
- This energy difference plays a critical role in metabolic pathways and cellular respiration.
