Study Notes
- Cellular respiration breaks down glucose to produce ATP for energy.
- Diffusion is the movement of molecules from high to low concentration.
- Organisms with high surface area to volume ratios can rely on diffusion for exchange.
- Humans have low surface area to volume ratios and rely on specialized exchange surfaces.
- The cell cycle has two phases: interphase and mitosis.
- Mitosis is a type of cell division for growth and repair.
- Mitosis does not produce sperm or egg cells (meiosis).
- Mitosis has four stages: prophase, metaphase, anaphase, and telophase.
- Spindles help move chromosomes during mitosis.
- New cells are formed with new nuclei during mitosis.
