The two basic forms of energy are ____________ and ____________ energy.
kinetic, potential
A calorie is the amount of heat required to raise the temperature of one gram of water by one degree Fahrenheit.
False . . . raise one gram of water by one degree Celcius.
Which of the following statements best describes the concept of entropy?
Every energy transformation leads to an increase in the amount of disorder.
Which of the following is not true regarding ATP?
A)It contains more energy after its terminal phosphate group has been removed.
The process of photosynthesis converts water and carbon dioxide into carbohydrates.
A)True.
Enzymes
C)accelerate chemical reactions.
The induced fit model of enzyme activity says that
D)the enzyme's active site changes in shape to allow for substrate binding.
Feedback inhibition is a cellular process in which two substrates compete for the active site of an enzyme.
B)False.
When a cell is placed in a hypotonic solution,
water moves across the plasma membrane (into the cell), but solute does not.
Facilitated diffusion differs from simple diffusion in that facilitated diffusion
B)requires proteins.
Active transport is the cellular process used to move molecules against
their concentration gradient towards a lower concentration.
B)False.
In a glass of iced tea, the tea and the sugar are
B)requires proteins.
The process by which vesicles are used to transport digestive enzymes and hormones out of the cell is called
A)exocytosis.
The process by which substances are brought into the cell by specific receptors is called
receptor-mediated endocytosis.
A ripe peach hanging from a tree branch
B)has potential energy
Carbohydrates and fats are used by the body to
convert ADP to ATP.
Which of the following has the least amount of energy available to humans?
D)chicken
Which of the following is not a type of passive transport?
A)osmosisB)diffusionC)facilitated diffusionD)plasmolysisE)movement of a solute across a plasma membrane towards a higher concentrationFeedback:
is an incorrect answer. Osmosis, diffusion, facilitated diffusion, and
plasmolysis are all passive transport requiring no energy.
Beaker A contains a 25% salt solution. A differentially permeable bag
(permeable to water, but not salt) containing 57% salt solution is
allowed to float on top of the solution in Beaker A. What will occur?
B)Water will flow from Beaker A into the bag.
Which of the following would occur to a plant if it were placed in a 75% sugar solution?
B)It would undergo plasmolysis.Because the plant was placed in a hypertonic solution, the plants cells will shrivel undergoing plasmolysis.
