energy - Answer all living things need ______ to move and grow chemical reactions (catabolic and anabolic) - Answer Energy comes from: Catabolism - Answer breakdown of complex molecules into smaller ones Anabolism - Answer reactions that build cells Coupling - Answer Catabolic and anabolic reactions can be done together/at the same time in order to use the energy released from catabolism to perform anabolism the microbial buffet - Answer catabolism is nicknamed: polysaccharides...

Where does the pentose phosphate pathway take place? - In the cytosol, of course. This makes sense because it starts off by using Glucose 6-phosphate, which is found in the cytosol for glycolysis et al. Does the pentose phosphate pathway generate ATP? - No. What is the usefulness of the pentose phosphate pathway? - It provides NADPH for various biosynthetic reactions and pentoses for nucleotide and nucleic acid synthesis. Where is the pentose phosphate pathway active? - It p...
