Enzymes are important to living things because they permit?

reactions to occur rapidly and at body temperature


How can photosynthesis be increased by increasing the temperature?

Temperature affects living things mainly by affecting the rate of chemical reactions. These are catalysed by enzymes, which are speeded up by increasing the temperature. The Calvin cycle is a series of chemical reactions, so increasing the temperature increases the rate of reactions in the Calvin cycle and so increases the rate of photosynthesis.


Why energy required for living things?

Living things need energy for several important processes that are vital to life. One of the most important is the growth and repair of cells and tissues - energy is required for the various biochemical reactions that achieve this.


What is important about enzyme catalysis in living organisms?

Enzymes are very important because they speed up the chemical reactions that are required for life.


How does temperaure affect living things?

Living organisms run on biochemical reactions, and these reactions are affected by temperature. Any chemical compound is going to break down at a sufficiently high temperature, and any liquid (other than helium) is going to freeze solid at a sufficiently low temperature. Every organism has an certain temperature range in which it functions most successfully.

What is the function of enzymed?

Enzymes specifically and selectively speed up [and control] each and all of the tens of thousands of biochemical reactions that {simultaneously} take place in all Living Cells.i.e enzymes are specifically involved in maintaining the oxidation level of glucose that occur in our body and in the maintaining body temperature

What Organic molecules that catalyze reactions in living systems are?

Enzymes are organic molecules that catalyze reactions in living systems.


Chains of chemical reactions in living organisms are called?

Bio-chemical reactions.


Why do living things need both endothermic and exothermic reactions in their bodies?

Living things have cellular reactions which involve both reactions in the process. Endothermic reactions help the body conserve energy or contain it. Exothermic reactions help the body produce energy.
