Answer:
A catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction. A catalyst will appear in the steps of a reaction mechanism, but it will not appear in the overall chemical reaction (as it is not a reactant or product).
Answer:
Tyrosine is a polar and aromatic compound. its side chain acidity and basicity is neutral
if a peptide contain only a string of tyrosine residue especially l tyrosine the solubility increases more
Explanation:
even tyrosine number remains constant, tyrosine containing peptide will be more soluble. This peptide is soluble in 1 M HCl (100 mg/ml), with heating. The solubility in water (25 °C) is 0.45 mg/ml in the pH range 3.2 - 7.5.
2.0 mg/ml; at pH 9.5, the solubility is 1.4 mg/ml; and at pH 10, the solubility is 3.8 mg/ml.
Answer: oprion <span>A. Catalysts can only increase the rate of reaction for compounds that do react.

Explanation:
Such as the right choice states a catalyst cannot make react two materials that cannot chemically react.
The catalysts modify the rate (speed) of a reaction between chemicals.
The definition of catalyst is a substance that increases the speed of a chemical reaction by modifying the activation energy but that is not consumed in the reaction.
Then three facts must be highlithed about catalyst:
1) Catalysts are not included in the chemical equation since they do not increase the amount of product that can be obtained (they do not change the theoretical yield of the reaction).
2) Catalysts change the path that the reactants take to yield the products, which is how the energy activation is changed.
3) As consequence, catalysts are not consumed during the reaction.
Answer:
Citrate synthase, acetyl-CoA
Explanation:
Beta oxidation is the process by which fatty acid molecules are broken down in prokaryotes' cytosol and in eukaryotes' Mitochondria to produce acetyl-CoA. The overall reaction in Beta oxidation is given below;
Cn-acyl-CoA + FAD + NAD^+ + H2O+ CoA ------------->Cn-2-acyl-CoA + FADH2 + NADH + H^+ + acetylCoA.
Beta-oxidation occurs by cleaving two carbons every cycle to form acetyl-CoA. It involves four process.
(1). Dehydrogenation of long chain fatty acids to create trans C2 and C3. This process is catalyzed by acyl CoA dehydrogenase.
(2). The hydration of Trans-delta2-enoyl CoA to produce L-3-hydroxyacyl CoA. This process is catalyzed by enoyl-CoA hydratase.
(3). The re-hydrogenation of L-3-hydroxyacyl CoA to produce 3-ketoacyl CoA in the presence of 3-hydroxyacyl CoA dehydrogenase.
(4). Thyolysis. In this process, thiolase enzyme catalyzes the reaction. A new molecule of coenzyme A breaks the bond by nucleophilic attack on C3.
