The answer is B. The higher the concentration of substrate, the FASTER a reaction happens (since there are more opportunities for molecules to collide in a way that favours the reaction), so B is an incorrect statement.
The other three options describe correct features of catalysts and/or enzymes (which are considered “biological catalysts”).
Answer:
Carbohydrate (monosaccharide)
Explanation:
Carbohydrates are one of the four biological molecules in nature. Carbohydrates are structurally composed of carbon, hydrogen and oxygen elements. However, these elements (C,H,O) are present in each carbohydrate in the ratio 1:2:1 respectively.
As stated in this question, glucose is an organic molecule made up of carbon, hydrogen and oxygen in the 1:2:1 proportion, hence, it is a CARBOHYDRATE. Since glucose possess one sugar component, it is classified as a MONOSACCHARIDE with a chemical formula C6H12O6.
Freshwater does not contain any salt, salt water does however contain salt.
