Handwritten Biology Notes

Need someone to write my school notes: CHAPTER 23 WS23.1 1. ENZYMES Source Name Digestive Function Salivary Amylase Breaks down starch into sugars Gastric Pepsin Breaks down proteins into peptides Pancreatic Amylase Breaks down starch into sugars Pancreatic Lipase Breaks down fats into fatty acids Pancreatic Protease Breaks down proteins into peptides Intestinal Peptidases Break down peptides into amino acids Intestinal Disaccharidases Break down sugars into monosaccharides Intestinal Lipase Breaks down fats into fatty acids Intestinal Enterokinase Activates trypsin for digestion 2. DIGESTIVE AIDS Name Source Digestive Function Hydrochloric Acid (HCL) Stomach Activates pepsin and kills bacteria Intrinsic Factor Stomach Helps absorb vitamin B12 Bile Liver/Gallbladder Emulsifies fats for digestion Mucus Stomach lining Protects digestive tract lining 3. HORMONES Name Source Digestive Function Gastrin Stomach Stimulates gastric juice release Cholecystokinin Small intestine Releases bile and enzymes Secretin Small intestine Neutralizes stomach acid 4. ESSENTIAL AMINO ACIDS Definition Amino acids are the building blocks of proteins. 9 Essential Amino Acids Histidine — growth and repair Isoleucine — energy production Leucine — muscle growth Lysine — immune support Methionine — metabolism Phenylalanine — brain chemicals Threonine — tissue health Tryptophan — serotonin production Valine — muscle repair 5. ESSENTIAL VITAMINS Definition Vitamins help the body grow and stay healthy. Fat-Soluble vs Water-Soluble Fat-soluble vitamins are stored in fat. Water-soluble vitamins are not stored long-term. 11 Essential Vitamins Vitamin A — vision Vitamin B1 — energy production Vitamin B2 — growth Vitamin B3 — metabolism Vitamin B6 — brain function Vitamin B12 — red blood cells Vitamin C — healing and immunity Vitamin D — strong bones Vitamin E — protects cells Vitamin K — blood clotting Folate — DNA production 6. ESSENTIAL MINERALS Definition Minerals help regulate body functions. 12 Essential Minerals Calcium — bones and teeth Phosphorus — energy production Potassium — muscle function Sodium — fluid balance Magnesium — muscle movement Iron — oxygen transport Zinc — immune system Iodine — thyroid function Copper — red blood cells Selenium — cell protection Fluoride — tooth protection Chloride — digestion 7. ESSENTIAL FATTY ACIDS Definition Fatty acids help with energy and cell growth. Omega-3 — supports brain and heart health Omega-6 — supports growth and skin health
