Study Notes
Mitochondrion Structure
- The mitochondrial inner membrane is the most permeable membrane of the mitochondrion.
Electron Transport Chain
- High-energy electrons are transferred to the electron-transport chain from activated carriers like NADH in oxidative phosphorylation in mitochondria.
- The low redox potential of NADH means that it has a high energy level.
Photosynthesis
- Stage 1 of photosynthesis uses an electron-transport chain to pump protons and make ATP.
- In photosynthesis, high-energy electrons come from light energy.
Chloroplast Structure
- The photosynthetic machinery is found in the thylakoid membrane of the chloroplast.
Signal Transduction Cascades
- One of the false statements regarding signal transduction cascades is not specified.
ATP Synthesis
- The proton flow through the transmembrane H+ carrier of ATP synthase results in the generation of ATP.
Cell Cycle Regulation
- Cyclin(s) regulate the cell cycle.
Mitochondrial Matrix
- The pH of the mitochondrial matrix is alkaline, which is higher than that of the intermembrane space.
