Study Notes
Characteristics of Life, Proteins, Chemistry of the Cell, Transport Mechanisms
- Characteristics of life include irritability, motility, metabolism, homeostasis, growth, and reproduction.
- The primary function of the cell membrane is to be semi-permeable, allowing some substances through while keeping others out.
- Mitochondria are the site of cellular respiration, where glucose and oxygen are converted into ATP and carbon dioxide.
- Proteins are made up of amino acids and have various functions, including structural support, antibody production, and enzyme activity.
- Enzymes are protein catalysts that speed up chemical reactions in the body.
- Mutations in genes can result in the production of different proteins, such as in the case of hemoglobin.
- Cancer is caused by mutations that lead to uncontrolled cell division, particularly in fast-dividing epithelial tissue.
- Mixtures can be separated by physical means, and can be homogeneous or heterogeneous.
- Solutions are homogeneous mixtures in which one substance is dissolved in another, such as saline or dextrose in water.
- Electrolytes, such as sodium, potassium, calcium, and iron, play important roles in nerve impulses, muscle contraction, and other physiological processes.
- Transport mechanisms in cells can be passive, such as diffusion and facilitated diffusion, or active, such as active transport.
- Osmosis is the diffusion of water across a semi-permeable membrane from an area of high concentration to an area of low concentration, to equalize the water content.
- Filtration is the movement of a solution through a membrane under mechanical force or pressure, such as in the kidneys.
