A change in body temperature will have which of the following effects on enzymes in the body? O A change in the ability of some enzymes to bind with their coenzymes
A change in the ability of some enzymes to bind with their substrate
A reduction in the concentration of some enzymes in the body
An increase in the concentration of some enzymes in the body

A reduction in the concentration of some enzymes in the body

Explanation:

As temperature is increased the enzymes and substrate gain kinetic energy (move more quickly). This increases the frequency of collisions and the formation of enzyme-substrate complexes. Therefore as the temperature is increased the enzyme activity and the rate of reaction increases.

Increases in temperature increase molecular activity, and can result in a higher rate of collisions between enzymes and substrates. If the temperature rises too high, however, the enzymes could become denatured, and the positive effects of the temperature increase could be nullified.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
