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
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
glucose—ANSWER-a simple sugar
, limiting factors—ANSWER-limit the rate of a reaction, for example light in
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
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
guard cells—ANSWER-surround the stomata in the leaves of plants and
control their opening and closing
haemoglobin—ANSWER-the red pigment that carries oxygen around the
body in the red blood cells
palisade mesophyll—ANSWER-the upper layer of the mesophyll tissue in
plant leaves made up of closely packed cells that contain many chloroplasts
for photosynthesis
phloem—ANSWER-the living transport tissue in plants that carries dissolved
food (sugars) around the plant
