Cell And Carbohydrate Metabolism

Question 1

Key features of glycolosis

Answer 1

• starting, end products and intermediates are C6 or C3
• no loss of CO2
• some C3 intermediates are used by the cell for specific things
• glucose is oxidised to pyruvate
• NAD+ is reduced to NADH
• Overall, it is exergonic process with -ve deltaG value
  All intermediates phosphorylated
• 2 moles ATP required to activate process, 4 produced, net yield of 2
• important substances produced from intermediates of glycolosis

Question 2

Carbohydrates are compounds that? (3 aspects)

Answer 2

• have the general formula (CH2O)n
• contain an aldehyde (-CHo) or keto (C=O) group in multipul hydroxyl groups (-OH)
• exist as mono, di and polysaccharide
