What is the role of enzymes in metabolism
|
Metabolism is all the chemical reactions that occur in the body, enzymes cause chemical reactions to proceed that would not normally
|
|
|
Enzymes chemical composition
|
Enzymes are organic catalysts.They contain carbon and is dirived from living things.All enzymes are proteins
|
|
|
What is pH
|
The pH is a figure given for acidity or alkalinity of a solution
|

Why is it important to maintain a constant internal environment for optimal metabolic efficiency
|
internal environment refers to the fluid surrounding living cells within a multicellular organism.
constant internal environment refers to the condictions present in this fluid which need to be kept at a constant level such as nutrients temperature water pH blood volume blood pressure oxygen carbon dioxide optimal metabolic efficiency means that the orgamism is functioning at its best. That is the metabolic process are occuring at their optimum rate Therefore,WHY IS A CONSTANT INTERNAL ENVIRONMENT NEEDED TO BE ABLE TO ACHIEVE OPTIMAL METABOLIC EFFICIENCY, metabolic reactions are catalysed by enzymes.therefore,if the metabloic reactions are to occur at an potimum level, then the enzymes must be working at their potimum level.enzymes work best underoptimum conditions such as a certain temperature and pH.Therfore, cells need to maintain constant internal conditions suited to the enzymes so that the metabolic proces in the body may occur at their optimum rate. |

Describe homeostasis
|
Homeostasis is the process by which organisms maintain a relatively stable internal state
