Four flasks, J, K, L and M, were set up to investigate the production of carbon dioxide during respiration. Limewater turns increasingly cloudy as more carbon dioxide is passed through it. Predict what would happen if only one worm was used in flask L. The limewater in flask
K would turn cloudy more slowly
K would turn cloudy more quickly
M would turn cloudy more slowly
M would turn cloudy more quickly.

The apparatus shown was used to investigate the rate of respiration in yeast at 20 °C. Which of the following changes would cause a decrease in the rate of respiration of the yeast?
Increase the thickness of the layer of oil by 1 mm.
Increase the temperature of the glucose solution by 1 °C.
Decrease the concentration of the glucose solution by 1%.
Decrease the volume of indicator solution by 1 cm3.
ATP is an energy-rich molecule formed by respiration.
Name a cellular process which requires energy from ATP.
(a)
Muscle cells contain many of which cell structure because they require lots of ATP.
(a)
Name one substance produced by a cell carrying out aerobic respiration.
(a)
Cellular processes occur in different parts of the cell. Name the energy producing process which starts in the cytoplasm and is completed in the mitochondria.
(a)
Which line in the table below identifies the direction of diffusion of the three substances during muscle contraction?
A
B
C
D
Muscle tissue can be dark or light in colour.
Dark tissue cells use oxygen to release energy.
Light tissue cells do not use oxygen to release energy.
Name the process by which energy is released in the dark tissue cells.
(a)
Name the substance which muscle cells break down to produce pyruvate.
(a)
