Presentation on theme: "REVIEW BIOLOGY 1 MYP VOCABULARY #3. PHOTOSYNTHESIS Is the overall process by which sunlight (solar energy) chemically converts water and carbon dioxide."— Presentation transcript:
GLYCOLYSIS A series of reactions using enzymes in which a glucose molecule is broken down into pyruvic acid molecules and two ATP molecules in the absence of oxygen.
AEROBIC RESPIRATION A process in which oxygen is required.
ANAEROBIC RESPIRATION A process in which oxygen is not required.
KREBS CYCLE The first step of aerobic respiration in which the pyruvic acid formed in glycolysis travels to the mitochondria where it is chemically transformed in a series of steps, releasing carbon dioxide, water, and energy (which is used to form 2 ATP molecules).
ELECTRON TRANSPORT CHAIN A series of chemical reactions ending with hydrogen combining with oxygen to form water (carbon dioxide is released as a waste product).
FERMENTATION A common anaerobic process which makes lactic acid or alcohol.
PHOSPHATE GROUP The three parts of ATP are nitrogenous base, ribose sugar, and __________________.
ATP-ADP CYCLE Losing or gaining a phosphate group to release or store energy is called
ORGANIC MOLECULES Proteins, Carbohydrates, and lipids are
CALORIC VALUE The number of calories per gram is called
PROTEINS Organic molecules that are used to repair tissues and cells.
CARBOHYDRATES Organic molecules that are used as the main source of energy.
LIPIDS Organic molecules that are used to store energy to use when needed.
