- respiration and co enzymes
- need for respiration
- all living things need energy fro metabolic reactions
- building large molecules and breaking large molecules
- active transport, secretion (exocytosis) , endocytosis
- replication of DNA, synthesis of proteins and organelles, movment, activation of chemicals
- ATP
- 3 x inorganic phosphates
- ribose
- adenine
- energy is released by releasing a phosphate group by hydrolysis
- NAD
- organinc non-protein molecule
- helps dehydrogenase enzyme carry out oxidation
- made of 2 linked nucleotides each having ribose and adenine
- when NAD accepts two H ions it is reduced
- NAD takes H ion from link reaction into the mitochondrial matrix to be pumped into inter membrane space for chemiosmosis
- FAD
- takes H ion to the mitochondrial matrix to be used in chemiosmosis
- FADH comes from krebs cycle
- Co enzyme A
- made from panthathetic acid, adenosine, 3x phosphate groups and cytosine
- carries acetate from link to krebs
- also carries acetate found in fatty acids and amino acids into krebs
- need for respiration
