6. Insulin
Insulin is a hormone that is central to regulating energy and glucose metabolism in the body. Insulin causes cells in the liver, muscle, and fat tissue to take up glucose from the blood, storing it as glycogen in the liver and muscle.

7. Hemoglobin
Hemoglobin is the iron-containing oxygen-transport oxygen in the red blood cells of vertebrates and the tissues of some invertebrates.

8. Cellulose
Cellulose is the structural component of the primary cell wall of green plants, many forms of algae. Cellulose is the most common organic compound on Earth. About 33% of all plant matter is cellulose (the cellulose content of cotton is 90% and that of wood is 40–50%

9. Glycogen General Characteristics polysaccharide, (C-6, H-10, O-5)
stored primarily in the liver and muscle tissue
readily converted to glucose as needed by the body to satisfy its energy needs
supplies energy during heavy work.
stored with water (1 gram of carbohydrates stored with 3 grams of water)
central nervous system (CNS) is dependent on hepatic glycogen for energy

12. Enzymes 
are biological protein-containing catalyst that speeds up the rate of chemical reactions without being involved in the reaction itself. They help complex reactions occur everywhere in our life. Whenever a substances is needed to be transformed into another, nature uses enzymes to simply speed up the process.

13. Enzyme Substrate Reaction

14. Lock & Key Mechanism

15. Lock & Key Mechanism
The active site on the enzyme attaches to a substrate molecule (such as a disaccharide) forming an enzyme-substrate complex. The enzyme is unaltered during the reaction and is free to catalyze the breakdown of another substrate molecule.

17. Acids
Acids are solutions that contain a higher concentration of H+ ions
pH valve range from 1– 3
Sour taste
Form H+ ions
Caused burns & corrosive
Example:
Stomach acid – Hydrochloric acid

18. Bases Base are Alkaline solutions pH range from 11-14 Bitter taste
Slippery to touch
Causes burns & corrosive
Produces the hydroxide ions (OH+)
Example: Lye & drain cleaner
