What is the best definition of metabolism?

A The rate at which chemical reactions occur in cells and the body

B The rate at which digestion occurs

C The speed at which toxins are broken down by the body

D The speed at which enzymes work in the digestive system

Why does the heart rate increase during exercise?

To increase glucose and oxygen supply to the muscles.

To increase the oxygen supply to the muscles

To increase the supply of carbon dioxide to the cells

To increase the supply of oxygen and urea to the cells.

Which of the following is an example of a metabolic reaction?

The formation of amino acids from glucose and nitrate ions

The reabsorption of water in the large intestine

The absorption of glucose in the small intestine.

The dilation of blood vessels when hot

What are the limiting factors of photosynthesis?

Light intensity, carbon dioxide and temperature

Carbon dioxide, water and temperature

Water, temperature, light intensity and carbon dioxide

Light intensity, carbon dioxide and water

Cellulose is made from glucose. What is its function?

To be used to build cell membranes

Which equation represents anaerobic respiration in plants and yeast cells?

D Glucose = ethanol + carbon dioxide

C glucose = carbon dioxide + water

Which of the following are true of the effects of temperature on photosynthesis?

At high temperatures lower than at where enzymes are denatured, respiration reduces yields from photosynthesis.

The rate of photosynthesis is greatest at high temperatures

The optimum temperature for photosynthesis in all plants is 37 °C.

In an investigation on photosynthesis, why did a student add sodium hydrogencarbonate to the water?

To decrease the temperature of the water

To keep the pH of the water constant

Which of the following best explains why a plant breeder placed open bags containing a fungus around his greenhouse?

The fungi will respire and release carbon dioxide into the greenhouse.

The fungi will increase the oxygen concentration in the greenhouse

Fungi in the soil encourage root growth in plants.

Which of the following are true about aerobic and anaerobic respiration?

Aerobic respiration produces much more energy per glucose molecule than anaerobic respiration

The products of anaerobic respiration contain less energy than the products of aerobic respiration

More species of organism obtain their energy anaerobically than aerobically.

Which of the following best explains why yeast is used to make bread?

The carbon dioxide produced by anaerobic respiration makes the dough rise.

The alcohol produced by anaerobic respiration adds flavour to the bread.

Yeast respires anaerobically to produce lactic acid, which produces the sour dough needed to make bread.

What is the function of the waxy cuticle?

Allow water to fall on leaf and glide off onto soil below

What happens to the rate of photosynthesis as the lamp is moved away from the pondweed?

Decreases as the number of bubbles decrease

Decreases as number of bubbles increase

Increases as the number of bubbles decrease

Increases as the number of bubbles increase

Give the uses of energy from respiration

Move molecules via active transport

Break down small molecules to large molecules

Give two similarities between anaerobic respiration in animals and plants

Both produce lactic acid and carbon dioxide

Why does a person's heart rate and breathing rate remain high after sprinting?

Glucose is incompletely broken down to lactic acid

Carbon dioxide and water are formed

Glucose is completely broken down
