Answer: An enzyme is a biological catalyst that speeds chemical processes. A substrate is the substance that reacts in contact with an enzyme. Enzymes are specific when reacting with a substrate
Explanation:
<em><u>Plants</u></em> : plants are generally <em><u>autotropic</u></em> living organisms, that prepare their own food by using simple substances through <em><u>photosynthesis</u></em>,
eg. maple, bamboo, etc.
<em><u>Consumers</u></em>: these are living organisms that doesn't produce their own food and depends upon <em><u>producers</u></em> and other <em><u>consumers</u></em> for food.
eg. Human, rat, etc
<em><u>decomposers</u></em> : these are living organisms that break down the <em><u>dead</u></em> and <em><u>decaying</u></em> body of organisms to obtain their food,
eg. bacteria, mushrooms, etc
<em><u>producers</u></em> : these are living organisms that produce their own food through process of <em><u>photosynthesis</u></em>.

Explanation:
Answer:
It decreases the levels of cAMP in the cell, repressing transcription from the lac operon.
Explanation:
When glucose is absent, cAMP serves as coactivator binds to CRP, the catabolite gene activator protein. The CRP-cAMP complex binds to the site near the lac promoter and stimulates the expression of the operon by RNA polymerase many folds.
Catabolite repression refers to inhibition of the synthesis of enzymes of lactose catabolism when glucose is present as an energy source. In the presence of glucose, synthesis of cAMP is inhibited resulting in its lower cellular concentration. The lower cAMP levels do not allow the binding of cAMP and CRP. The result is reduced expressed of lac operon.
