Study Notes
Electron Transport Chain and ATP Synthesis
- FMN, ubiquinone, cytochrome c1, and oxygen are involved in electron transport. Ubiquinone receives electrons from NADH.
- Chemiosmosis is defined as the movement of hydrogen ions across a mitochondrial membrane, critical for ATP production.
ATP Synthase Functionality
- ATP synthase (F1F0 ATP synthase) is a membrane-embedded protein complex that synthesizes ATP by adding phosphate to ADP using energy from protons diffusing through it.
Role of Prosthetic Groups
- Prosthetic groups (or cofactors) are molecules that bind to proteins and aid in their functionality, contributing to enzymatic reactions or structural stability.
Ubiquinone in Cellular Respiration
- Ubiquinone acts as a soluble electron transporter within the electron transport chain, linking the first or second complex to the third.
Fermentation Types
- Lactic acid fermentation is the method that can occur in animal skeletal muscles, distinguishing it from other fermentation types like alcohol and mixed acid fermentation.
Fermentation Versus Anaerobic Respiration
- Fermentation primarily relies on glycolysis, while anaerobic respiration utilizes glycolysis, the citric acid cycle, and electron transport with an alternative final electron acceptor, differentiating it from fermentation which does not involve these mitochondrial processes.
Anaerobic Cellular Respiration
- Anaerobic cellular respiration allows organisms to convert energy in the absence of oxygen, enabling survival in low oxygen environments.
Definition of Fermentation
- Fermentation is a process that regenerates NAD+ using either organic or inorganic compounds as final electron acceptors, occurring when oxygen is not present.
