BIOL 1201 Chapter : Exam 1 (Photosynthesis/Respiration)
Document Summary
Refer to all slide for pictures and diagrams, etc. Synthesis of atp: readily available energy: refer to diagram, adp + energy + p (inorganic phosphate) = atp, energy doesn"t just pop out of thin air, ex. Breakdown of atp: releasing energy for work: atp = energy p = adp. Coupled reactions within living cells: glucose (refer to diagram on phone, 1st reaction gives off energy, 2nd reaction stores energy, 3rd reaction releases energy. Electron carriers (refer to diagram on phone: ex. Nad: typed of nucleotide, excited electrons can be transferred. How is metabolism controlled: enzymes regulate chemical reactions, cells couple reactions, energy carriers capture energy from exergonic reactions and deliver to endergonic reactions. Proteins that catalyze a reaction: enzymes, end in -ase. Catalysts: speed up chemical reactions, enzymes are biological catalysts, usually proteins, sometimes other things, like rna. Activation energy: controls rate of reaction: refer to picture on phone.
