B4 Bioenergetics Flashcards
Endothermic reaction
A reaction that requires transfer of energy from the environment
Glucose
A simple sugar
Limiting factor
limit the rate of a reaction, for example photosynthesis
Photosynthesis
the process by which plants make glucose and oxygen using carbon dioxide, water, and light
Chloroplast
Site of photosynthesis
Chlorophyll
Enzyme which controls photosynthesis
Aerobic respiration
an exothermic reaction in which glucose is broken down using oxygen to produce carbon dioxide and water and
release energy for the cells
Anaerobic respiration
an exothermic reaction in which glucose is broken down in the absence of oxygen to produce lactic acid in animals
and ethanol and carbon dioxide in plants and yeast. A small amount of energy is transferred for the cells
Exothermic reaction
a reaction that transfers energy to the environment
glycogen
carbohydrate store in animals
Lactic acid
the end product of anaerobic respiration in animal cells
Oxygen dept
the extra oxygen that must be taken into the body after exercise has stopped to complete the aerobic
respiration of lactic acid
