Study Notes
Alcoholic Fermentation
- During alcoholic fermentation, pyruvate is reduced via a two-step process that regenerates NAD+ and produces carbon dioxide as a byproduct.
Mitochondria
- Mitochondria are dynamic energy-converting organelles that house the enzymes for glycolysis and the citric acid cycle.
- Porins in the inner mitochondrial membrane contain beta-sheets in their transmembrane domains, allowing moderately-sized molecules to pass through membranes.
- Protein complexes of the electron transport chain generate a proton gradient across the inner mitochondrial membrane.
NAD+
- Nicotinamide adenine dinucleotide (NAD+) becomes reduced when it gains electrons.
Hydrolysis Reaction
- Water is required for a hydrolysis reaction.
Lipid Rafts
- Lipid rafts are characterized by... (no additional information provided)
Cell Membrane
- ...function like a fence to block membrane protein movement between various regions of an intestinal epithelial cell membrane.
Endosymbiosis
- Endosymbiosis proposes that mitochondria and chloroplasts evolved from prokaryotic cells.
