What is a good analogy for cell transport across the cell membrane?
Swiping an ID card to enter a building
A public park that anyone can visit
a door that locks behind a person exiting a building
a door that someone cannot open
What is the result of diffusion across a membrane?
higher concentration of the solute on the outside of the cell than inside
higher concentration of the solute on the inside of the cell than outside
equal concentrations of water on both the inside and outside of the cell
equal concentrations of solute on both the inside and outside of the cell
What is the advantage of the cell wall during osmosis?
It prevents an animal cell from bursting
It allows a plant cell to be in a hypotonic state without bursting
It keeps water out of the cell
the cell wall has nothing to do with osmosis
What happens to an animal cell when placed in distilled water
It will shrink and shrivel up
It will undergo mitosis
It will increase in size until it ruptures
It is not affected by distilled water
Name 3 types of active transport
difusion
osmosis
facilitated diffusion
endocytosis
exocytosis
protein pump
anerobic
aerobic
fermentation
mitosis
meiosis
vegetative budding
What is requires for active transport to occur?
energy
oxygen
carbon dioxide
water
What is the movement of particles in passive transport?
from low to high concentration
from high to low concentration
no movement of particles
particles move equally
What is the main goal of cell transport?
To maintain homeostasis and equillibrium
to make energy
to help the cell divide
to make proteins
What are the reactants for photosynthesis?
Oxygen + water
carbon dioxide + water + sunlight
glucose + oxygen
ATP + sunlight
Which substance affects the rate of photsynthesis the least
glucose
oxygen
water
sunlight
What are the products of photosynthesis?
glucose + oxygen
Carbon dioxide + water
oxygen + water
carbon dioxide + sunlight
What is the role of chlorophyll in photosynthesis?
absorb water
absorb sunlight
exchange oxygen
breakdown glucose
What part of plants would you expect to have the highest concentration of chloroplasts?
roots
stems
leaves
xylem
Compare anerobic and aerobic respiration
aerobic respiration uses oxygen and makes more ATP
anaerobic respiration uses oxygen and makes more ATP
anaerobic is an active process and aerobic is passive
aerobic and anaerobic are the same
What are the reactants of cellular respiration?
oxygen + glucose
carbon dioxide + water
sunlight + water
carbon dioxide + glucose
How is fitness related to respiation?
The more fit the person, the greater the oxygen debt
the more fit the person, the greater the lactic acid buildup
the more fit the person, the longer anerobic respiration occurs.
the more fit the person, the greater the time before anerobic respiration is required
Why is there an increase in your number of breaths as activity increases?
as activity increases, more oxygen is exhaled
as activity increases, breathing becomes more effeicient
as activity increases, the oxygen needs of cells increased
as activity increases, the rate of heart beating increases
How is stored energy in adenosine triphosphate (ATP) released?
by releasing adenosine in ATP
by trapping ATP from carbohydrates
by breaking a phosphate bond in ATP
by combining ATP molecules in chlorophyll
What is the cause of muscle pain after a lengthy exercise?
a buildup of ethanol due to aerobic respiration
a buildup of ethanol due to anaerobic respiration
a buildup of lactic acid due to aerobic acid
a buildup of lactic acid due to anaerobic respiration
The energy supplied by ATp is derived from the breakdown of molecules of
glutamate
glycerol
glycolysis
glucose
