Enzymes
Cards in this deck (9)
- 1What are enzymes and what do they do?They are a protein that functions as a biological catalyst, which speeds up a chemical reaction.
- 2What is the lock and key model?Where the shape of the active site of the enzyme matches the shape of its substrate molecules.
- 3What causes enzymes to denature?High temperatures or extremes of pH levels
- 4What happens when an enzyme denatures?The shape of it changes, meaning it can no longer work.
- 5What is the optimum temperature for an enzyme and why?Roughly 37-40 degrees for humans, as if it is too cold there are fewer collisions between enzymes and substrates, and if it is too hot the enzyme will denature
- 6What enzyme breaks down starch, and to what?Amylase breaks it down into maltose
- 7What enzyme breaks maltose down, and to what?Maltase breaks it down into glucose
- 8Which enzymes breaks proteins down, and to what?Pepsin and trypsin (Proteases) breaks it down into amino acids
- 9What enzyme breaks fats down, and to what?Lipase breaks it down into fatty acids and glycerol
