Bioenergentics

• What do you use glucose for

  Cellulose

  join with nitrates to make amino acids

  stored as lipids (in plants as seeds)

  stored as starch in roots (insoluble)

  if not the cell would swell up with water if there were lots of glucose
• Why is a large temp bad for photosynthesis

  Enzymes denature

  slower rate
• Word equation for photosynthesis

  carbon dioxide+water (sunlight)——->glucose+oxygen

  endothermic
• Why do organisms need energy

  Chemical reactions to build larger molecules

  movement

  keeping warm
• Anaerobic respiration in humans

  Glucose—->lactic acid
• Anaerobic respiration in plants


  Glucose—->ethanol+carbon dioxide

  transfers less wenrgy oxidation if glucose incomplete
• Anaerobic resp in yeast


  Fermentation

  alcohol

  bread
• What does metabolism include

  Glucose—>starch,glycogen,cellolose

  firm lipids from a molecule of glycerol and three molecules of fatty acids
• Metabolism include


  Glucose and nitrate ions amino acids used to synthesise protein

  repiration

  break excess proteins to form urea for excretion
• What plant used snd ehy

  Pondweed o2 corresponds rate photosynthesis
• Where does lactic go via blood to get converted to glucose

  Liver
• What does lactic acid get brokfn fown by

  oxygen into co2 h2o
• What does energy from respiration maintsin

  Body temp
• What is respiration

  Cells release energy from glucose
