Enzymes are organic catalysts‚ usually proteins that speed up metabolic reactions. They lower the amount of energy needed for reactions to progress in cells. In enzymatic activity‚ the molecules at the beginning are called substrates. Lactose metabolism is when lactose is destroyed‚ maintained or produced. For instance‚ being lactose intolerance that’s where lactose is destroyed. Metal cofactors in enzyme activity are required to function properly. The Effect of Temperature on Enzymatic Activity:

[pic] THE KNIFE by Richard Selzer One holds the knife as one holds the bow of a cello or a tulip: by the stem. Not palmed nor gripped nor grasped‚ but lightly‚ with the tips of the fingers. The knife is not for pressing. It is for drawing across the field of skin. Like a slender fish‚ it waits‚ at the ready‚ then‚ go! It darts‚ followed by a fine wake of red.

There are three types of muscle skeletal which are voluntary‚ smooth muscle which are involuntary and cardiac muscle. Muscle is made up of protein filaments‚ myosin and actin. These filaments slide past each other to produce a contraction which changes both the length and shape of the cell. The primary function of the muscle is to produce both movement and force. Skeletal muscle is composed of bundles of muscle fibres containing myofibrils of thick and thin filaments (myosin and actin). Skeletal
