Question
In your own words, define the following terms and answer everything in parentheses:
1) Non-biological catalyst (what does it do? Give an example, and indicate if they are generally specific or non-specific):
2) Biological catalyst (what does it do? Give an example, and indicate if they are generally specific or non-specific):
3) Substrate in an enzymatic reaction:
4) Reactant in a chemical reaction:
5) Product of a chemical or enzymatic reaction:
6) Active site of an enzyme:
7) Catabolism:
8) Anabolism:
9) Endergonic:
10) Exergonic:
11) Gibb’s free energy (G):
12) Delta G (DG; explain how you would calculate it):
13) Negative delta G (-DG):
14) Positive delta G (+DG):
Explanation / Answer
1) Non-biological catalyst ( increase or decrease the rate of a chemical reaction but themselves remain unchanged; potassium permanganate; Non-biological catalysts are not specific in their action and produce bad residues after the reaction)
2) Biological catalyst (they increase the rate of a chemical reaction; Pepsin; biological enzymes are specific and give rise to good products)
3) The molecule upon which an enzyme reacts is called substrate
4) In a chemical reaction, reactants are chemical substances that are converted into products.
