Document Summary
Check slide 3 lecture 8 for more reference. Slide 4/8: video based on how enzymes work. Slide 6: cellular metabolism cells need energy for their activities. Metabolism intracellular chemical reaction: all the reaction/chemistry happen in our body. Enzymes play a vital role in metabolism: helps speed up chemical reaction (catalytic) Coenzymes enzymes helpers": help the enzymes to do better. Slide 7: enzymes and substrates fit together physically. 2 substrate molecule (blue and red) substrates contacting active site of enzyme (blue and red -> green) they bind tightly to enzymes active site product molecule (red and blue = purple molecule) enzymes doesn"t change. Slide 9: 2 main types of metabolic pathways (know for test) Slide 10: atp/adp cycle last slide to know for the test (know both names) Cells use atp constantly and so atp must be always replenished. Photosynthesis: carbon dioxide and water are converted into carbohydrates (mostly sugars)
