enzymes

• Enzymes


  Proteins that lower the activation energy required for a reaction to take place
• Enzymes


  • They are catalysts which means they do not get used up in a chemical reaction
  • They are substrate specific which means an enzyme can only act on one specific substrate
• Lipids (triglycerides)


  Comprised of glycerol and three fatty acid molecules
• Ribosomes


  Their function inside a cell is protein synthesis from mRNA
• Active processes


  Require energy to move against the concentration gradient and occur in carrier proteins
• Passive processes


  Do not require energy to move along the concentration gradient and occur in the phospholipid bilayer
• Availability of enzymes need to be maintained to ensure that there is an availability of active sites
• Products of a reaction must be removed as they take up / decrease space
• Pyruvate from glycolysis


  1. Gets converted into lactic acid

  2. Gets sent to the liver

  3. Stored in muscles
• Mitochondria


  • Consist of folds that increase the organelle's surface area, allowing for more aerobic respiration reactions to occur
