Semester Test Review ● ● ● ● ● ● CHONP Importance of Carbon Macromolecules (Carbohydrate, Lipid, Protein, Nucleic Acid) ○ Carbohydrate: Sugar, glucose, energy, CHO 1:2:1 ○ Lipid: Phospholipid, store energy, CHO ○ Protein: Amino Acids, CHON ○ Nucleic Acid: Nucleotides, DNA and RNA, CHONP Photosynthesis: Process by which producers turn light energy into chemical energy ○ Producers (plants) only, Chloroplast of the cell ○ CO2 + H2O Sunlight ---> O2 + C6H12O6 ○ Plants convert CO2 into O2 for consumers and make Glucose (food) for themselves and consumers. ○ Removes carbon dioxide and releases oxygen. ○ Photosynthesis is limited by the amount of CO2, sunlight, temperature, and wavelength. Cellular Respiration: Process by which chemical energy is converted into usable energy. ○ All life, so plants and animals, Mitochondria in eukaryotes ○ O2 + C6H12O6 ---> CO2 + H2O + ATP ○ The main purpose is to convert glucose (food) into usable energy in the form of ATP. ○ Removes oxygen and releases carbon dioxide. ○ Aerobic Respiration: Normal type that uses oxygen ○ Anaerobic Respiration: Alternative that does not require oxygen, also called fermentation ■ Alcoholic fermentation: makes alcohol as byproduct; yeast, alcohol, bread ■ Lactic Acid fermentation: makes lactate as byproduct; muscles, bacteria, yogurt Ecology ○ Food chain and web ○ Energy and biomass pyramid ○ 10% rule ○ Predation, Competition ○ Symbiosis: Mutualism, Commensalism, Parasitism ○ Carrying Capacity ○ Limiting factors for population growth
