Study Notes
Cell Physiology
- Mitochondria are the powerhouses of the cell, responsible for producing ATP.
Cell Division
- Mitosis is a type of cell division.
- Interphase occurs before mitosis or meiosis and consists of:
- Preparation for cell division
- DNA replication
- Cell growth and preparation for division
Cell Division Types
- Meiosis produces:
- 1 egg cell and 3 polar bodies in females (F:23)
- 4 sperm cells in males (M:23)
- The purpose of meiosis is to reduce the number of chromosomes by half.
Nerve Physiology
- Action potential is a key event in nerve function.
Muscle Physiology
- Muscle contraction involves:
- Voluntary muscle contraction
- Action potential in nerve
- Muscle contraction events:
- Excitation-contraction coupling
- Muscle fiber contraction
Organic Compounds
- Examples of organic compounds include:
- Fructose
- Galactose
- Glucose
Ion Channels
- Potassium is an important ion involved in nerve function.
