• What is the word equation for aerobic respiration?

  glucose + oxygen à water + carbon dioxide
• In which part of the cell does aerobic respiration take

  place?

  mitochondria
• In humans, where does the glucose needed for

  respiration come from?


  From the digestive system where is it absorbed

  from food.
• In humans, where does the oxygen needed for respiration

  come from?

  Oxygen breathed into the lungs is carried to cells by the

  blood.
• How is the carbon dioxide removed from the human

  body?

  Blood carries it away from the cells to the lungs
• Energy from respiration is needed to grow and

  repair proteins. What type of molecules join

  together to form proteins?

  amino acids
• Plants use energy to turn glucose into cellulose. What do

  plants use cellulose for?

  to strengthen cell walls
• What is the difference between aerobic and anaerobic

  respiration?

  aerobic respiration involves oxygen

  anaerobic respiration occurs without oxygen
• Identify 3 minerals plants need for healthy growth:

  magnesium nitrates phosphates
• When does anaerobic respiration occur?

  during vigorous exercise
• Where in the cell does anaerobic respiration

  take place?

  cytoplasm
• Why is the heart rate and breathing rate still

  high for a few minutes after you’ve finished

  sprinting?

  there is an oxygen debt after

  hard exercise. Oxygen is needed

  to break down the lactic acid.
• What is the equation for photosynthesis?

  water + carbon dioxide à glucose + oxygen
• What parts of the plant cell responsible for

  photosynthesis?

  chloroplasts
• What is the name of the green pigment that

  supports photosynthesis?

  chlorophyll
• what is the word equation for anaerobic respiration in humans

  glucose à lactic acid
• where are palicade cells found in the leaf


  near the top (so the sunlight

  can reach them)
• why do palisade cells have lots of chloroplast

  so lots of glucose can be produced

  from photosynthesis.
• What transports water and minerals up a

  plant?

  xylem
• What transports sugars (glucose) around a

  plant?

  phloem
• How does anaerobic respiration in yeast help

  us make bread?

  the carbon dioxide forms bubbles

  to make bread ‘fluffy’\
• How does anaerobic respiration in

  yeast make alcohol.?

  The ethanol produced is the

  alcohol used in drinks and gels
• What are the pores on the underside

  of leaves called?

  stomata
• How do they help a plant to perform

  photosynthesis?


  they allow gas exchange (carbon

  dioxide and oxygen)
• what is the word equation for anaerobic respiration in yeast

  glucose à ethanol + carbon dioxide
