Discuss briefly, the different factors that can affect the rates of chemical reactions in our body.

Factors that can affect the rate the rates of chemical reactions in the body are temperature, substrate concentration and presence and absence of enzymes.

Explanation:

Rate of a reaction may be defined as the speed of the reaction or the rate at which reactants are converted into products.

Increase or decrease in the range of temperature can affect the rate of a chemical reactions of the body. With increase in the temperature the rate of a reaction increases as the effective collision between the substrate increases and then decreases.

Enzymes are the biocatalyst that can increase the rate of a chemical reaction. The absence of the enzymes decreases the rate of a reaction.

The increase in the concentration of substrate increases the rate of a chemical reaction of the body.

good thing- during decomposition the organic molecules in organic matter are broken down into simpler organic molecules that require further decomposition or into mineralised nutrients

bad thing- it can be harmful in crop productivity

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
