1. 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
2. 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
3. exothermic reaction: a reaction that transfers energy to the environmen
4. glycogen: carbohydrate store in animals
5. lactic acid: the end product of anaerobic respiration in animal cells
6. oxygen debt: the extra oxygen that must be taken into the body
after exercise has stopped to complete the aerobic respiration of
lactic acid
7. Mitochondria: Organelle that is the site of respiration
8. Responses to exercise: Heart rate increases, Breathing rate increases,
glyco- gen in muscles is converted to glucose
9. endothermic reaction: a reaction that requires a transfer of energy
from the environment
10.glucose: a simple sugar
11.limiting factors: limit the rate of a reaction, for example photosynthes
12.photosynthesis: the process by which plants make food using carbon
dioxide, water, and light
13.Reactants for photosynthesis: water and carbon dioxide

, 14.Products of photosynthesis: glucose and oxygen
15.Chloroplast: Site of photosynthesis
16.white blood cells: Blood cells that perform the function of
destroying dis- ease-causing microorganisms
17.Sperm cells: 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.
18.light: energy source for photosynthesis
19. aorta: the artery that leaves the heart from the left ventricle and
carries oxy- genated blood to the body
20.arteries: blood vessels that carry blood away from the heart. They
usually carry oxygenated blood and have a pulse
21.atria: the upper chambers of the heart
22.capillaries: the smallest blood vessels. They run between individual
cells and have a wall that is only one cell thick
23.coronary arteries: the blood vessels that supply oxygenated blood to
the heart muscle
24. double circulatory system: 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
25.epidermal: the name given to cells that make up the epidermis or
outer layer of an organism
26.guard cells: surround the stomata in the leaves of plants and
control their opening and closing
