Lactose intolerance is caused when your body has a deficiency of an intestinal enzyme that splits lactose into other forms like glucose, glucose, or sugars that allows this to be absorbed by the intestine. The most likely reason for this condition is that it was inherited from a family member with the same genetic disorder.
Answer:
Explanation:
Enzymes are biological catalysts; catalysts are substances that increase the rate of chemical reactions without being used up (BBC, 2010), without these catalysts it would take an extremely long time for these reactions to take place. The enzyme used in this particular experiment was pepsin; pepsin is a zymogen of pepsinogen. Pepsinogen is activated by hydrochloric acid, which is released from parietal cells in the stomach lining. The hormone gastrin and the vagus nerve trigger the release of both pepsinogen and hydrochloric acid from the stomach lining when food is ingested. Hydrochloric acid creates an acidic environment, which allows pepsinogen to unfold and cleave itself in an autocatalytic fashion, generating pepsin. (Life Science Network, 2010)
A lot can be learnt about enzymes by studying the rate of enzyme catalyzed reactions, these rates of reaction can be studied in various ways. In this experiment, using a range of different temperatures, the enzyme pepsin will be mixed with egg albumen. This is high in protein and bound to the dye Coomassie blue to gain a light absorbance reading using a spectrophotometer and in effect see how much protein has been digested by the pepsin.
The correct answer is C. Populations of organisms rarely change over time
Explanation:
In biology, living organisms differ from non-living ones according to different features, this includes the ability to replicate or reproduce sexually or asexually; the metabolization of energy to different activities such as growth or reproduction; a complex system that allows them to live and the ability to adapt to the environment. This last idea implies organisms and populations of them change over time according to the environment and therefore the one that is not a property of life is that "populations of organisms rarely change over time".
