Question 27 of 38

1

Select from the dropdown lists to complete the text.

The limiting factors for photosynthesis are ( light, colour ) intensity, ( carbon dioxide, oxygen ) concentration and ( temperature, water availability ).

As these increase, the rate of photosynthesis steadily ( increases, decreases ) up until a certain point where it ( plateaus, suddenly peaks ) off and the limiting factor ( changes, stays the same ).
Temperature
When it is too ( low, high ), enzymes are ( dormant, active ), when it is too ( hot, low ), enzymes are ( denatured, killed ).

Question 35 of 38

3

Select from the dropdown lists to complete the text.

The enzyme ( amylase, amilase ) is produced by the ( salivary, pitruatry ) glands, the ( pancreas, liver ) and the ( small, large ) intestine. This enzyme catalyses the breakdown of ( starch, lipids ) into ( sugars, amino acids ) in the ( mouth, stomach ) and ( small, large ) intestine.

( Protease, Priteose ) enzymes are produced by the ( stomach, mouth ), the ( pancreas, liver ) and the small ( intestine, hyperglands ). These enzymes catalyse the breakdown of ( proteins, starch ) into ( amino, fatty ) acids in the ( stomach, mouth ) and ( small, large ) intestine. They work best in ( acidic, alkaline ) conditions, hence the stomach also produced ( hydrochloric acid, Sodium hydroxide ).

( Lipase, lapose ) enzymes are produced by the ( pancreas, liver ) and the ( small, large ) intestine. These enzymes catalyse the breakdown of ( lipids, starch ) into ( fatty, amino ) acids and ( glycerol, glucose ) in the ( small, Large ) intestine. These work best in ( alkaline, acidic ) conditions thus the ( liver, gall bladder ) produces ( bile, hydrochloric acid ), which is stored in the ( gall bladder, liver ), that is then secreted into the ( small, large ) intestine. This also ( emulsifies, breaks down ) the fats to ( increase, decrease ) the surface area and ( increase, decrease ) the rate of digestion.

Explanation

Explanation

Question 38 of 38

1

How are enzymes used in Industry?

Select one or more of the following:

  • Protease are used to 'pre-digest' the protein in some baby foods

  • Carbohydrates are used to convert starch into sugar syrup

  • Isomerase is used to convert glycol syrup into fructose syrup, which is sweeter so less in needed (slimming foods)

  • Lipases are used to covert lipids into glycerol which is thicker so less is needed (slimming foods)

  • Protease is used to catalyse the reaction of respiration in cloning clinics

  • Amylase is used to pre-digest starch in pet food
