| Question | Answer |
| What is metabolism? | Metabolism encompasses the integrated and controlled pathways of enzyme-catalysed reactions within a cell. |
| What are the two metabolic pathways? | • Anabolic Pathway • Catabolic Pathway |
| Describe a anabolic pathway | • Require energy • Involved in bio-synthetic processes making complex molecules from simpler ones. • Example: protein synthesis |
| Describe a catabolic pathway | • Releases energy • Involved in the breakdown of complex molecules into simpler ones. • Example: aerobic respiration |
| Give an example an anabolic reaction | • Glucose-1-phosphate ---> Starch • Enzyme: phosphorylase (potato) |
| Give an example of a catabolic reaction | • Starch ---> Maltose • Enzyme: Amylase |
| What is a synthetic pathway? | Known as a Anabolic Pathway |
| Which is irreversible? | |
| Which is reversible? | |
| Give an example of a metabolic pathway | • Glycolysis • Converts glucose to an intermediate metabolite called pyruvate |
| What is the alternative route? | • Sorbitol - which bypasses steps controlled my enzyme A,B and C. |
