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. The flesh parts‚ falling away to yellow globules of fat. Even now‚ after so many times‚ I still marvel at its power--cold‚

D2. Explain the importance of homeostasis in maintaining the healthy functioning of the body. Homeostasis is vital for the maintenance of healthy functioning of the body. It is important the body keeps to a narrow range of variables‚ and without it ‚ chemical reactions and metabolic processes within the body cannot be carried out properly‚ which can cause disease and complications. If the body cannot maintain its temperature‚ this can cause the person to overheat‚ resulting in hyperthermia. This

Comparative Vertebrate Anatomy Lecture Notes - Skeletal System II (Skull) The Vertebrate Skull consists of: 1 - neurocranium (also called endocranium or primary braincase) 2 - dermatocranium (membrane bones) 3 - splanchnocranium (or visceral skeleton) Neurocranium: 1 - protects the brain 2 - begins as cartilage that is partly or entirely replaced by bone (except in cartilaginous fishes) Cartilaginous stage: neurocranium begins as pair of parachordal & prechordal cartilages below the

cardiac action potential differs significantly in different portions of the heart. The heart is provided with a special excitatory system and a contractile system necessary to perform this function. This differentiation of the action potentials allows the different electrical characteristics of the different portions of the heart. For instance‚ the specialized excitatory system of the heart has the special property of depolarizing without any external influence with a slow‚ positive increase in voltage

Biology Digestive Enzyme Experiment “Design an experiment in which you will investigate a digestive enzyme’s effect on digestion” Research Question: To determine the effect of enzyme concentration on the rate of digestion. This will be done by increasing the concentration of the enzyme diastase and investigate its effect on the rate of starch digestion. The rate will be determined by the amount of time it takes to completely digest the powdered starch‚ the complete digestion will be indicated by

Chapter 1: Introduction to Human Anatomy and Physiology I. Introduction A. The interests of our earliest ancestors most likely concerned injuries and illness because healthy bodies demand little attention from their owners. B. Primitive people certainly suffered from occasional aches and pains‚ injuries‚ bleeding‚ broken bones‚ and diseases. C. Before agriculture‚ infectious diseases did not spread easily because isolated bands of people had little contact with each other. D. With agriculture
