Question 2

The final electron acceptor of aerobic respiration is ________.

Accepted Answer

A)  ATP
B)  oxygen
C)  lactic acid
D)  NAD⁺

Question 3

When oxygen delivery becomes insufficient to support a runner's aerobic metabolism,cells switch to an emergency mode in which ________.

Accepted Answer

A)  ATP is generated less efficiently by harvesting the heat energy in a cell
B)  ATP is inefficiently produced and lactic acid is generated as a by-product
C)  lactic acid is broken down to produce smaller amounts of ATP
D)  carbon dioxide is joined with water to generate much smaller amounts of ATP

Question 4

Some friends are trying to make wine in their basement.They've added yeast to a sweet grape juice mixture and have allowed the yeast to grow.After several days,they find that sugar levels in the grape juice have dropped,but there's no alcohol in the mixture.The most likely explanation is that ________.

Accepted Answer

A)  the mixture needs more sugar; yeast need a lot of energy before they can begin to produce alcohol
B)  the mixture needs less oxygen; yeast only produce alcohol in the absence of oxygen
C)  the mixture needs more oxygen; yeast need oxygen to break down sugar to produce alcohol
D)  the mixture needs less sugar; high sugar concentrations stimulate cellular respiration,and alcohol is not a by-product of cellular respiration

Question 5

What are (is) the main factor(s) causing differences between the chick hatch weight and the weight of the egg when it is laid?

Accepted Answer

A)  The only factor that causes the chick to weigh less than the egg when it is laid is the removal of the shell.
B)  Not only does the hatchling have no shell,but it has lost some of its mass (weight) to the air during development.
C)  During development,the chick gains new parts so the weight increases.
D)  Egg weight at oviposition includes a lot of water that evaporates during development.

Question 9

Several students were talking about which came first in the history of the Earth.Which student has the best understanding of what happened?

Accepted Answer

A)  Photosynthetic producers must have come first to provide food for other organisms.
B)  Anaerobic bacteria must have come first because there was no carbon dioxide in the atmosphere.
C)  Photosynthetic producers must have come first to provide oxygen for other organisms.
D)  Anaerobic organisms must have come first because there was no oxygen in the atmosphere.

Question 10

Accepted Answer

A)  2
B)  6
C)  38
