AQA GCSE Biology Unit 2.4

1

Which of these is the correct, general, word equation for aerobic respiration?

1

Which of these is the correct, general, balanced symbol equation for aerobic respiration?

1

What is the "unit" of energy in the cell, released by respiration?

1

True or false? Mitochondria have a folded inner surface to maximise their surface area for enzymes to carry out aerobic respiration.

1

True or false? Active cells, such as muscle cells, need few mitochondria as these release more energy from respiration than the mitochondria in inactive cells.

1

Which of these would not be an ethical way of showing that peas respire?

1

Which of these activities are important uses of the energy from respiration?

1

True or false? Muscles are made up of bundles of fibres.

1

What name is given to pairs of muscles which contract in opposite directions to produce movement?

1

What do animals store excess glucose molecules as?

1

True or false? Carbon dioxide must be removed from the blood because it lowers blood pH.

1

Which of these effects occur to the cardiovascular system when you exercise?

1

Which of these effects occur to the respiratory system when you exercise?

1

Why do humans sometimes undergo anaerobic respiration?

1

Which of these is the correct, general, word equation for anaerobic respiration in humans?

1

Which of these is the correct, general, word equation for anaerobic respiration in yeasts?

1

True or false? Lactic acid stimulates the muscles to continue exercising.

1

True or false? Anaerobic respiration is inefficient as glucose is not completely broken down.

1

Why do you continue to puff and pant after you have stopped using your muscles for a long period of time?

1

What is the oxygen debt?
