Which statement best describes a relationship between enzymes and a simple biological reaction? a) enzymes will increase the amount of substrate formed during a biological reaction. b) enzymes will decrease the amount of substrate formed during a biological reaction. c) a reaction rate can be increased when the specific enzyme for a biological reaction is present. d) a reaction rate can be decreased when multiple enzymes for a biological reaction are present.

The Option C is correct.

By increasing the enzyme concentration, the maximum reaction rate greatly increases.

Conclusions:

The rate of a chemical reaction increases as the substrate concentration increases. Enzymes can greatly speed up the rate of a reaction. However, enzymes become saturated when the substrate concentration is high.

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.

2. scott sand can improve his soil quality by incorporating more silt and organic matter into the soil. peat moss and organic matter can also be incorporated.
