  • Q2

    what is the word equation for respiration?

    carbon dioxide + water --> glucose + oxygen

    glucose + oxygen -->  carbon dioxide + water

  • Q3

    what is anaerobic respiration?

    respiration with oxygen

    respiration without oxygen

  • Q4

    what is aerobic respiration?

    respiration with oxygen

    respiration without oxygen

  • Q5

    What type of reaction is respiration?

    exothermic, releases energy

    endothermic, takes in energy

    mitochondria

    cytoplasm

  • Q8

    what is respiration used for?

    basic functions of life, building up larger molecules from smaller ones, break down larger molecules into smaller ones, muscles contract, keeping internal temperature constant and in plants to transfer mineral ions throughout the plantbasic functions of life, building up larger molecules from smaller ones, break down larger molecules into smaller ones, muscles relax, keeping internal temperature constant and in plants to transfer mineral ions throughout the plant

  • Q9

    how is excess glucose stored in our bodies?

    glucagon

    glycogen

  • Q10

    what happens when we exercise?

    more respiration needs to occur, breathing rate increases to take more oxygen in and remove carbon dioxide, heart rate increases to provide muscles with more oxygen and glucose for the increased respiration

    less respiration needs to occur, breathing rate increases to take more oxygen in and remove carbon dioxide, heart rate increases to provide muscles with more oxygen and glucose for the decreased respiration

  • Q11

    what happens when you exercise?

    glucagon is broken down into glucose to supply cells with fuelglycogen is broken down into glucose to supply cells with fuel

    glycogen is broken down into glucose to supply cells with fuel

  • Q12

    when does anaerobic respiration occur?

    when you exercise hard

    when walking

  • Q13

    which releases more energy: aerobic or anaerobic?

    aerobic

    anaerobic

    30s
  • Q14

    in animal cells what is produced from anaerobic respiration?

    lactic acid

    ethanol and carbon dioxide

    30s
  • Q15

    what is muscle fatigue?

    when muscles are used slowly for a short time, lactic acid builds up because of anaerobic respiration

    when muscles are used vigorously for a long time, lactic acid builds up because of anaerobic respiration
