Q

enzyme overview

A
  • Activation Energy - energy needed to start reactions
  • Enzymes work to lower activation energy by weakening chemical bonds so that chemical reactions can occur quicker
  • More enzymes → less activation energy
  • Specific and reusable

Q

structure and process of an ezyme

A
  • Substrate - molecule that the enzyme will work on
  • Active Site - specific shaped area on the enzyme that matches substrate
  • Enzyme grabs onto substrate via active site
  • Catalysis - substrate is broken down/combined with another molecule to make something new
  • Enzyme then lets to of substrate, which is now the product

Q

influential factors

A
  • Substrate Concentration
    - More substrate → faster rate of reaction until point of saturation
  • Temperature/pH (Acidity/Basicity)
    • Enzyme most active at optimum temperature and work best at specific pH
    • Temperatures/pH outside of optimum → lower enzyme activity/enzyme denatures
