What is the function of the vacuole?
to take up space
to store wastes and water
to store our DNA
to make proteins
What does the chloroplast do for plants?
allows them to change color with the seasons
to allow them to make proteins
to allow them to make their own food
to allow them to replicate their DNA
Which of the following determines the function of a specialized cell?
the way it was developed
the active genes in the cell
temperature
what type of organism the cell develops in
What happens during cell differentiation?
different parts of the genes are activated to create different shapes and functions
the cells mutate into different cells
different parts of the genes are deleted which causes strange cell shapes
the cells do not undergo differentiation, DNA does
What is the function of a red blood cell?
to travel through the body
to carry nucleic acids throughout the body
to carry oxygen throughout the body
to carry electrical impulses through the body
ATP is required to make the acids needed in the stomach for digestion. The ATP helps move large molecules from the blood (low concentration) to the stomach lining (high concentration). What type of cell transport is this?
passive
osmosis
diffusion
active
Placing a wilted leave into water will have it inflate again. What is happening during this process?
diffusion allows water to move into the leaf
active transport moves water out of the leaf
active transport allows water to move into the leaf
osmosis allows water to move into the wilted leaf
A freshwater plant is placed in the ocean. What will most likely happen to the cells of this plant?
the cells will swell
the cells will shrink
the cells will explode
the cells will reach equilibrium
ATP is being rapidly consumed in the membrane near a protein. What type of transport is most likely occurring?
passive
active
diffusion
osmosis
Molecules moving from high to low are taking part in _________ transport.
passive
active
Cells work constantly to keep their water, oxygen, pH, and glucose concentrations level at all times. What is this an example of?
balance
homeostasis
harmony
diffusion
Which row demonstrates active transport?
1
2
3
4
Which way is water (the star) moving?
Out of the cell
Into the cell
water is at homeostasis
water is at equilibrium
Why is glucose moving into the cell?
glucose is at equilibrium it is not moving
glucose moves from low to high and so it will move out of the cell to reach equilibrium
glucose is not in this image
glucose moves from high to low and there are hardly any glucose in the cell vs outside
Contractile vacuoles pump water out of cells to help maintain balance. What is the energy source of the contractile vacuole?
the sun
ATP
glucose
caffeine
A red blood cell is put in a beaker that has a high salt concentration. What will happen to the red blood cell?
it will swell
it will shrink
nothing
it will explode
How does shivering when cold help maintain homeostasis?
it causes you to make more ATP
it does not contribute to homeostasis
it helps regulate body temperature
it allows you to make more heat cells
Why do we need carbohydrates in our diet?
because they taste good
because carbs help us create lipids to keep us warm in the winter
because carbs make proteins
because we need the carbs to break down and use for energy
Which of the following are a polysaccharide?
glucose
DNA
starch
glycerol
What is the function of this macromolecule?
insulation
builds muscle
provides energy
contributes to DNA
Some plants have very waxy, shiny leaves. This allows water to slide off the leaf instead of being absorbed. Which macromolecule created the wax on the outside of the leaf?
nucleic acids
proteins
lipids
carbohydrates
Which of the following is a monomer of a protein?
nucleotides
glucose
amino acids
monosaccharides
Which statement describes a characteristic of molecule Z?
it changes shape with each substrate
it functions at a specific pH
molecule Z is an example of a lipid
molecule Z is made of DNA
Lactase is an enzyme that breaks down lactose. If someone doesn't have lactase in their system, which macromolecule will they have a hard time breaking down?
nucleic acids
proteins
carbohydrates
lipids
Why do rates of reactions involving enzymes decrease if the temperature gets too high?
the enzyme is too hot to work
enzymes work at any temperature
the enzyme becomes denatured by the high temperatures
the substrates change into products at high temperatures
Which process occurs in the mitochondria?
cellular respiration
photosynthesis
Which statement best first anaerobic and aerobic respiration?
Anaerobic respiration takes place in the chloroplast while aerobic takes place in the mitochondria.
anaerobic respiration makes 2ATP and aerobic makes 36ATP
anaerobic respiration takes place in the cytoplasm and aerobic respiration takes place in the nucleus
anaerobic and aerobic occur in the same location and make lactose
Which set of terms identifies the letters to describe this chart?
1
2
3
4
Which of the following describes a relationship between photosynthesis and cellular respiration?
the products of respiration are the reactants of photosynthesis
photosynthesis makes yeast for cellular respiration
cellular respiration creates oxygen for plants
the products of photosynthesis are the reactants of respiration
Elodea is a water plant studied for photosynthesis. The plant is producing bubbles in the test tube. Along with making oxygen, what else is being made in the test tube?
