Anaerobic respiration: glucose oxidized - ANS energy and byproducts. Glycolysis mechanism - ANS 6 carbon glucose-> 2 pyruvate molecule (3 carbon molecules). Net of ATP and 2 NADH, NADP+ will pick up electrons which will shuttle it to electron chain, NADH shuttling electrons from one place to another, taking electrons from glucose molecule and taking them to electron transport chain. Where does glycolysis occur and does it need oxygen? - ANS in the cytosol, no it ...

Explain why misconceptions about the nature of life, such as the theories of spontaneous generation or preformation, slowed our understanding of heredity and genetics. - ANS SPONTANEOUS GENERATION - the idea that new life had to come from old life, so life was spontaneously produced from non-living substances - ex: maggots came from dead meat, flies came from fruit - disproved by Redi when he covered a Petri dish filled with mean with a cloth and he left one exposed to the open air; f...
