Energy and ATP 4.5 / 5 based on 2 ratings ? BiologyBiological moleculesASAQA Created by: Betsy_2018Created on: 05-12-16 19:12 What is ATP? A nucleotide 1 of 14 What type of macromolecule is ATP? A phosphorylated macromolecule 2 of 14 What is the name of the pentose sugar in the ATP macromolecule? Ribose 3 of 14 What is the nitrogenous base of ATP Adenine (A) 4 of 14 What is ATP broken down by? ATP Hyrdolase 5 of 14 What is ATP formed by? ATP Synthase 6 of 14 How much ATP does a cell typically hold? A few second's worth (it is continuously made) (only released in small amounts) 7 of 14 Why is ATP good as an immediate energy source? Smaller; simple, single-step hydrolysis to break down unstable phosphate bonds (that repeal each other); more manageable energy source than glucose 8 of 14 Why is ATP more manageable than glucose? Its breakdown produces small amounts of energy (enough for its functions) without surplus energy 9 of 14 Why are the phosphate bonds so easily broken? It has a low activation energy; phosphate groups repel each other (3-) charge; ATP is unstable 10 of 14 What is the stage of photosynthesis where the synthesis of ATP occurs? Photophosphorylation 11 of 14 What is the stage of respiration where the synthesis of ATP occurs? Oxidative Phosphorylation 12 of 14 What is substrate-level phosphorylation? When a donor molecule transfers a phosphate group to ADP 13 of 14 What are the 5 uses of ATP? 1. metabolic processes; 2. movement; 3. active transport; 4. secretion (formation of lysosomes); 5. activation of molecules (e.g glycolysis) 14 of 14
