1.1 Living within a express mail temperature range
Most organisms have a limited temperature range within which they can be active.



One important reason for this is the biological chemicals called enzymes control the chemical reaction that make up each organism’s metabolism.

1.1.1 Enzymes
Enzymes are:
& fudge;Found in living things (they are biological chemicals)
•Catalysts that change the rate of chemical reactions (most useful catalysts speed up reactions)
•Proteins
•Active within a limited range of sensible and chemical conditions
•Very specific (each enzyme is involved in only one kind of chemical reaction)
• undeniable in very small amounts because they are used everyplace and over again
Enzymes names usually end with – ase; for example, catalse, sucrase and lipase. The name often (but not always) identifies the substrate, or...If you want to get a bountiful essay, order it on our website: Orderessay
