Organic Chemistry/Biochemistry 1: Compounds Important to Life • Biologists classify compounds into organic compounds and inorganic compounds. Organic Compound: a compound that is derived from living things and contains carbon Inorganic Compound: a compound generally derived nonliving things • Water Water is an inorganic molecule with unique properties that make it one of the most important compounds for living things. In the water molecule (H2O)‚ the hydrogen and oxygen atoms bond

Chapter I Introduction Photosynthesis is the process by which autotrophic organisms convert light energy to chemical energy in the form of glucose. Without this process life on earth would be very different because every organism directly or indirectly depends on photosynthesis. Photosynthesis helps the plants to grow roots‚ leaves‚ flowers and fruits. It is an extremely important process because plant tissue serves as the bottom of every food chain. The process of photosynthesis is dictated

intensely respiration happens faster and the muscles need more oxygen. Anerobic respiration uses a reaction of glucose and water to make energy it creates by-products of water and carbon dioxide (glucose + oxygen → carbon dioxide + water (+ ATP or C6H12O6 + 6O2 → 6CO2 + 6H2O) There will come a point when aerobic respiration isn’t enough‚ the body needs to respire anaerobically. In this glucose is directly broken down ion to ATP by the body this creates a byproduct of lactic acid. (glucose → lactic

to fuel the organisms’ activities. Photosynthesis is the chemical reaction that takes place in plants. Photosynthesis is also an enzyme controlled reaction. The chemical formula for the process of photosynthesis is: 6CO2 + 12H2O C6H12O6 + 6O2 The process of photosynthesis uses sodium dioxide and water to form glucose and oxygen. This experiment will measure the effect of the concentration of sodium bicarbonate with the pondweed and the rate of photosynthesis. The increased

amounts of palmitic acids are found in butter and cheese which is known for excessive weight gain for many who eat these foods with palm oil. Another unhealthy preservative found in unhealthy foods is Fructose. The chemical formula for fructose is C6H12O6 (National center for biotechnology information). Fructose is commonly used as sweetener for beverages‚ in medications and other synthetic products. Glucose also known as blood sugar is used for cellular respiration. Glucose‚

Summer Assignment – AP Biology – Chapters 2-5 Chapter 2 1. CHNOPS are the six most crucial elements in most macromolecules. Name them. Carbon‚ Hydrogen‚ Nitrogen‚ Oxygen‚ Phosphorous‚ Sulfur. 2. Create a chart and state how many bonds each of the CHNOPS elements can form. Carbon | Hydrogen | Nitrogen | Oxygen | Phosphorous | Sulfur | 4 | 1 | 3 | 2 | 3 or 5 | 2 | 3. Create a Venn Diagram to compare and contrast polar covalent bonds‚ nonpolar covalent bonds‚ and ionic bonds.

A carbohydrate is an organic compound that consists only of carbon‚ hydrogen‚ and oxygen‚ usually with a hydrogen:oxygen atom ratio of 2:1 (as in water); in other words‚ with the empirical formula Cm(H2O)n. The carbohydrates (saccharides) are divided into four chemical groupings: monosaccharides‚ disaccharides‚ oligosaccharides‚ and polysaccharides. In general‚ the monosaccharides and disaccharides‚ which are smaller (lower molecular weight) carbohydrates‚ are commonly referred to as sugars.

Name: Cellular Respiration—An Overview All cells need energy all the time‚ and their primary source of energy is ATP. The methods cells use to make ATP vary depending on the availability of oxygen and their biological make-up. In many cases the cells are in an oxygen-rich environment. For example‚ as you sit and read this sentence‚ you are breathing in oxygen‚ which is then carried throughout your body by red blood cells. But‚ some cells grow in envi¬ronments without oxygen (yeast
