• aerobic respiration . Answer: 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 . 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
• arteries . Answer: blood vessels that carry blood away from the heart.
They usually carry oxygenated blood and have a pulse
• atria . Answer: the upper chambers of the heart
• capillaries . Answer: the smallest blood vessels. They run between
individual cells and have a wall that is only one cell thick
• coronary arteries . Answer: the blood vessels that supply oxygenated
blood to the heart muscle
• double circulatory system . Answer: the circulation of blood from the
heart to the lungs is separate from the circulation of blood from the heart
to the rest of the body
