A  glycolysis, the reactions on the electron transport chain, and the Krebs (citric acid) cycle

B  glycolysis, oxidation, and the Calvin cycle reactions 

C  substrate inhibition, catabolism, and fermentation

D  hydrolysis, active transport, and the light reactions

E  None of the above is correct.

A  liver 

B  pancreas

C  salivary glands

D  stomach

A  break down food chemically.

B  break down food physically.

C  prepare undigested material and waste for disposal.

D  carry food to the stomach. 

A  The absorptive surface of our gut lets all materials pass through it into the bloodstream.

B  We are able to directly absorb most large nutrient molecules such as starch.

C  The human gut is able to absorb complex proteins easily.

D  We must process nutrients in order to absorb them. 

A  You always eat more food than you need.

B  Digestion increases the volume of food that initially enters the body.

C  The exit of the digestive system, known as the urinary tract, is needed to get rid of liquids you don’t digest.

D  Not all that you ingest is digested and absorbed, this “leftover” must be eliminated. 

E  None of the above are correct.

A  is kinetic energy that has not yet been turned to heat.

B  contains less energy than kinetic energy.

C  is stored energy unavailable to do work.

D  transfers motion to matter.

E  is contained in matter placed in certain positions or arrangements. 

A  the trachea 

B  the alveoli

C  the bronchioles

D  the tracheoles

A  Oxygen is moved by active transport from the lungs to the deoxygenated (“used”) blood in the capillary beds, and carbon dioxide is moved by active transport from the blood to the alveoli. 

B  Carbon dioxide is moved by active transport from the lungs to the deoxygenated (“used”) blood in the capillary beds, and oxygen diffuses from the blood to the alveoli.

C  Carbon dioxide diffuses from the air into the deoxygenated (“used”) blood in the capillary beds, and oxygen diffuses from the blood to the alveoli.

D  Oxygen diffuses from the air into the deoxygenated (“used”) blood in the capillary beds, and carbon dioxide diffuses from that blood to the alveoli.

E  Oxygen is moved by active transport from the lungs to the deoxygenated (“used”) blood in the capillary beds, and carbon dioxide diffuses from the blood to the alveoli.

A  alveoli. 

B  pharynx.

C  trachea.

D  bronchi.

A  Diffusion is very slow over all but the shortest distances, so oxygen must be delivered to our cells to speed up the process

B  Humans do not need as much oxygen as small organisms do, so we use inefficient transport systems like the circulatory system rather than diffusion.

C  Diffusion does not occur in organisms that have more than about 300 cells 

D  Humans need an internal transport system in order to quickly replace oxygen that is lost because of our high surface area of skin

A  veins.

B  arteries.

C  lungs.

D  ventricles. 

A  a carbohydrate.

B  a protein. 

C  a nucleotide.

D  a  lipid.

A  serve as a buffer

B  be stored temporarily as glycogen 

C  be broken down into simple sugars

D  be converted into fructose and linked together

E  be converted into starch

A  the constant state of the body

B  the varying of the body state within a narrow range

C  the ability to maintain an absolutely constant internal body state

D  the ability to maintain the internal body state within a narrow range 

E  . the ability to produce heat and maintain an internal temperature.

A  positive feedback 

B  negative feedback

C  hibernation

D  the lowering of a set point

E  hypothermia
