Homeostasis and Biochemistry REVIEW

Molecules Starch is made from molecules of – Simple Sugars Proteins are made from molecules of – Amino Acids What metabolic Activity Builds Larger Molecules from smaller ones Synthesis

What metabolic activity breaks down large molecules into smaller ones Digestion (Hydrolysis) When Carbohydrates are digested what is the end product Simple Sugars (Glucose) What are carbohydrates used for Source of Energy

When Proteins are digested what is the end product Amino Acids What do we then do with the amino acid – Synthesize them into our proteins What important protein controls metabolism Enzymes Where did you get the amino acids to make your enzymes The foods you eat

Enzymes What is the job of Enzymes All chemical reactions (Digestion, Synthesis etc.) What are enzymes made of Proteins So what are the building blocks of enzymes Amino Acids Every enzymes acts upon only One Substance

Enzymes work only in specific conditions like Temperature pH Concentration

Hormones What are they Chemical Messengers Where do the messengers go to Cells What on the cells do they interact with Receptors Why are only certain cells affected by hormones Cells have specific receptors

Receptors They work according to their – Shape Play an important role in communication between Cells

Feedback Mechanisms Maintain Homeostasis

  Person is outside and their body temperature decreases   Person is outside and their body temperature decreases The person begins to shiver and blood vessels in the skin constrict Body Temperature increases

 Carbohydrate
