photosynthesis and respiration

• is photosynthesis endo or exothermic

  endothermic
• word equation for photosynthesis

  carbon dioxide + water = glucose + oxygen
• symbol equation for photosynthesis

  6)CO2 + 6)H20 = C6H1206 + 6)02
• 4 factors affecting photosynthesis

  temperature, co2 concentration, light, chlorophyll
• uses of glucose - plants (4)

  respiration, fat or oil for storage, produce cellulose for the cell wall, amino acids for proteins
• is respiration endo or exothermic?

  exothermic
• word equation for anaerobic respiration

  glucose -> lactic acid
• aerobic respiration

  glucose + oxygen -> carbon dioxide + water
• which type of respiration is complete oxidation of glucose and which is incomplete

  aerobic - complete anaerobic - incomplete
• uses of energy - human(4)

  keeping warm, active transport, movement, chemical reactions to build larger molecules
• fermentation word equation

  glucose -> ethanol + carbon dioxide
• two uses of fermentation

  making bread, making alcoholic drinks
• which process is this - exothermic, gives out energy, uses oxygen, produces co2, happens in mitochondria

  respiration
• which process is this - endothermic, takes in light energy, produces oxygen, uses co2, happens in chloroplasts

  photosynthesis
• 3 short term effects of exercise

  increase in heart rate, breathing rate and breath volume
• why does oxygen debt occur

  when anaerobic respiration occurs, lactic acid builds up in the muscles and need to be taken to the liver and converted back into glucose
