●● anaerobic respiration
Answer: 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
Answer: a reaction that transfers energy to the environment
●● glycogen
Answer: carbohydrate store in animals
●● lactic acid
Answer: the end product of anaerobic respiration in animal cells
●● oxygen debt
Answer: the extra oxygen that must be taken into the body after exercise
has stopped to complete the aerobic respiration of lactic acid
,●● Mitochondria
Answer: Organelle that is the site of respiration
●● Responses to exercise
Answer: Heart rate increases, Breathing rate increases, glycogen in
muscles is converted to glucose
●● endothermic reaction
Answer: a reaction that requires a transfer of energy from the
environment
●● glucose
Answer: a simple sugar
●● limiting factors
Answer: limit the rate of a reaction, for example photosynthesis
●● photosynthesis
Answer: the process by which plants make food using carbon dioxide,
water, and light
●● Reactants for photosynthesis
Answer: water and carbon dioxide
, ●● Products of photosynthesis
Answer: glucose and oxygen
●● Chloroplast
Answer: Site of photosynthesis
●● white blood cells
Answer: Blood cells that perform the function of destroying disease-
causing microorganisms
●● Sperm cells
Answer: It has a long tail and a streamlined head to help it swim. There
are a lot of mitochondria in the cell to provide the energy needed. It also
carries enzymes in its head to digest through the egg cell membrane.
●● light
Answer: energy source for photosynthesis
●● aorta
Answer: the artery that leaves the heart from the left ventricle and
carries oxygenated blood to the body
