Questions

• Name U W Z

  W- Cristae

  Z- inner membrane space

  
• Describe the production of ATP by substrate level phosphorylation in different stages of respiration and reference number of ATP molecules produced

  Glycolysis is the first stage of respiration where 2 ATP molecules are produced from the break down of triose bisphosphate. 4 ATP are made but 2 are reused for glycolysis. 1 ATP is also produced per turn of the kerbs cycle, when a 5 carbon compound is converted to a 4 carbon compound (oxaloacetate)
• What is the precise location of link reaction within Cells

  Matrix of mitochondrion
• What properties of mitochondrial inner membrane allows chemiosmosis to occur


  The membrane is mainly impermeable to protons so they can accumulate. It has a large SA and the presence of ATP synthase which protons pass through
• Outline his ATP is produced in mitochondria by chemiosomosis

  The protons accumulate in the inter membrane space to create a proton gradient. The protons flow down a concentration gradient from the intermembrane space to the matrix through ATP synthase. ATP synthase catalyses the formation of ATP from ADP and Pi
• Which organ is lactate transported to and how does it reach this organ

  To the liver in the blood
