Respiration 1 of 18 Is respiration a gradual or rapid release of energy? Gradual 2 of 18 What does respiration provide the energy to produce? ATP 3 of 18 What is ATP? A nucleotide 4 of 18 What three things does ATP consist of? An organic base, adenine, a 5-carbon sugar, ribose and a sequence of 3 phosphate groups linked together 5 of 18 Which bonds are unstable and easily broken? The ones between the phosphate groups 6 of 18 What happens when the bonds between the phosphate groups are broken? A considerable amount of energy is released 7 of 18 Which phosphate is usually removed in living cells? The third one 8 of 18 What enzyme catalysts the reaction of ATP To ADP? ATPase 9 of 18 The conversion of ATP TO ADP is what type of reaction? Reversable 10 of 18 What is the equation for the removal of a phosphate group from ATP? ATP +water = ADP + Pi + energy 11 of 18 What is activation energy? The energy needed to start a chemical reaction 12 of 18 What is phosphorylation? The addition of phosphate to ADP 13 of 18 What is the equation for phosphorylation? Energy + P1 + ADP = ATP + water 14 of 18 What are the three forms of phosphorylation? Oxidative phosphorylation, photophosphorylation and substrate-level phosphorylation 15 of 18 Where does oxidative phosphorylation occur? On the membranes of mitochondria during aerobic respiration 16 of 18 Where does photophosphorylation occur? On the membranes of the chloroplasts during photosynthesis 17 of 18 When does substrate- level phosphorylation occur? When phosphate groups are transferred from donor molecules to ADP to make ATP 18 of 18
