Biochemistry and Metabolism
- Define metabolism
- Metabolism; the sum total of all the biochemical reactions taking place in
the cells of an organism
- May be involved with breaking larger molecules into smaller ones-
catabolic reactions (digestion)
- May involve building smaller molecules into larger ones- anabolic
reactions (muscle growth)
- State the functions of biological molecules in organisms
- Carbohydrates; energy storage
and supply
- Proteins; structure, transport, enzymes,
antibodies
- Lipids; Membranes, energy supple, thermal insulation,
protective layers, electrical insulation in neurons
- Vitamins and minerals; form parts of some larger molecules and
take part in metabolism reactions, act as coenzymes
- Nucleic acids; information molecules, carry instructions for life
- Water; takes part in many reactions, support plants,
solvent for most metabolic reactions, transport
- Organic chemistry is the study of chemical reactions that involve
carbon- carbon atoms bond together to form long chains and rings
- Forming a framwork atom that can form the basis of all the biological molecules necessary for life
