Metabolism
Chapter 8, exam 3- metabolism
| Question | Answer |
|---|---|
| Define metabolism | sum of all chemical reactions in a cell/organism |
| Define metabolic pathways | each reaction's product becomes the next reaction's starting point, with different enzymes catalyzing each step |
| how are metabolic pathways different from single chemical reactions | like assembly lines where each product feeds the next step, with different enzymes working at each stage |
| What are substrates/reactants in chemical reactions | the starting materials in a chemical reaction |
| What are products in chemical reactions | final substances produced at the end of a chemical reaction |
| What are catabolic pathways? | reactions that break down larger molecules into smaller molecules and release energy |
| What are anabolic pathways? | reactions that assemble small molecules into larger macromolecules and biomass and uses energy |
| What are similarities between anabolic and catabolic pathways? | both part of metabolism, involving biochemical reactions crucial for life |
