- Metabolic reactions
- Anabolic
- when smaller molecules join to form a larger molecule
- Catabolic
- when a large molecule is broken down to smaller ones
- some energy from this reaction is released as heat
- controlled by enzymes
- organisms should maintain the right temp for the enzymes to work properly

- living organisms need to respire why?

- controlled by enzymes
- energy= is the ability to do work
- potential energy is stored energy found in complex organic molecules
- kinetic energy is the movement energy when molecules can diffuse down their concentration gradients
- energy comes from photoautotrophs
- Respiration: the process where energy that is stored in complex organic molecules is broken down to prduce ATP
- ATP is a phosphorylated nucleotide it is made up of adenine + ribose sugar + 3 phosphates, is the universal energy currency
- role is to provide energy to all metabolic reactions, can be hydrolysed to ADP + Pi (inorganic phosphate) releasing 30.6 kJ energy per mol
- processes needing energy are: active transport of molecules and ions into and out of cell membranes, secretion, endocytosis
