What results from the removal of a phosphate group from ATP?
the production of mechanical energy
the release of energy
the creation of energy
the absorption of energy by chlorophyll
Infer why chloroplasts are found mostly in the leaves of plants.
he large surface area of leaves allows for maximum light absorption.
The waxy coating on the surface of leaves helps prevent evaporation.
Chlorophyll interferes with the xylem and phloem in the stems and trunks of plants.
The large surface area of leaves allows for contact with oxygen.
Upon watching the trees in your yard, you notice that there is a change in the climate. Those green leaves have begun to turn orange red and yellow.Why are leaves green except for in the autumn?
Could it be that the number of daylight hours is greater in the summer than in the fall? When the hours of daylight gets shorter, the production of chlorophyll stops.
Could it be that Chlorophyll molecules are the largest of the all pigment molecules.
Does Chlorophyll reproduces faster than the other pigments.
Is it because Green is the color of the spectrum most easily seen by humans.
When light strikes chlorophyll molecules, they lose electrons, which are ultimately replaced by which of the following?
Could it be that the electrons come from the breakdown of water at Photosystem II?
it is the fixing of carbon during the Calvin Cycle making it usuable for the production of C6H12O6.
Enzymes cause the glucose to break down and release electrons.
breaking down ATP
The energy acquired in photosynthesis is used to make glucose. Where is the glucose made in plants?
Is the glucose made in the thylakoid membranes?
Maybe the glucose is made in the mitochondria
Since the glucose occurs during the light independent reactions, and all photosynthetic actions occur inside the chloroplast, I believe that it is assembled in the stroma of the chloroplast.
Since there is no chlorophyll outside the chloroplast I believe that the production of glucose begins here in a process called glycolysis.
The Calvin Cycle is not controlled by the amount of sunlight received. The Calviin cycle can occur day or night. What is the connection between the Light Dependent Reactions and the Light Independent Reactions of the Calvin Cycle?
The Calvin cycle depends on products of light reactions.
Carbon dioxide is not available at night.
It is too cold at night for reactions to take place.
Most plants do not make the 4-carbon compounds that would be needed for the Calvin cycle to occur at night.

Specialized structures that carry out specific cell functions are called:

What exactly is an organelle?
The organelle is a multi-purpose structure that performs whatever job is needed by the cell.
The organelle contains the Genetic instructions for the entire cell.
An isolated worksite that performs one specific function for the cell.
The organelle is a tiny structure that provides food for the cell.

What role does Cholesterol play in the phospholipid bilayer?
Holds the two phospholipid layers together.
Provides food for the cell membrane
Acts as a lubricant for transport proteins.
Acts as a self destruct mechanism for the cell.
These structures will form a channel, or a carrying mechanism, to allow passage through the cell membrane
Transport Proteins
Cholesterol lubricated pumps
Phospholipids
Sodium potassium pumps
This type of protein is needed to move things by active transport across the membrane
Channel Proteins
Pumps
Carrier Proteins
Cholesterol lubricated passageways
What type of environment are cells found in?
The cells are surrounded by a liquid layer of interstitual fluid.
The cells are surrounded by a jelly - layer of cytosol.
The cells are embedded in a solid matrix of blood and bone.
The cells are surrounded by air that we breath in
All cells are surrounded by a nutrient rich fluid called
Interstitial Fluid
Cytoplasm
Cholesterol
Fatty acids
Cytosol
The outermost layer of a plant cell
Cell Wall
Centrioles
Chloroplast
Cell membrane
Explain why animal cells, including human cells, do NOT have a Cell Wall.
Animal cells would be unable to move nutrients by diffusion from the interstital fluid. They would also be unable to move waste by diffusion out of the cell.
Animal cells communicate with other cells by way of Carbohydrates in the cell membrane. A cell wall would hinder this communication system.
A cell wall only allows movement into the cell. Animal cells must be able to release waste as well and accept nutrients.
All cells actually do have a cell wall. In animal cells, the cell wall is very thin. This allows for diffusion of nutrients and waste to occur.
These organelles are Photosynthetic. They create Sugar molecules for energy storage.

Consider the movement of a solute across the membrane. The area of greater solute is always called the:
Hypertonic area
Hypotonic area
Isotonic Area
Bubonic Area
The Distillation Area
When you have the same amount of solute leaving a solution and you have entering a solution, then the solution is said to be
Hypertonic
Hypotonic
Isotonic
Bubonic
Distillated
When waste is created, a vacuole will capture the waste and take it to the cell membrane. Here the plasma membrane of the vacuole merges with the plasma membrane of the cell. Contractions occur and the waste is spewed back out into the interstitual fluidl.
Endocytosis
Exocytosis
allowing certain substances to pass through when there is a concentration gradient and a need for the nutrient.
Semi permeable
Selectively permeable
How does the cell get the new protein out of the transport VESICLE and into the interstitual fluid?
The plasma membrane of the transport vesicle merges with the plasma membrane of the cell. The transport vesicle then opens up and the protein is then released into the intersitial fluid.
The transport vesicle contains a sharp needle like structure which tears a whole in the plasma membrane. Then, using injection, the protein is propelled into the interstitial fluid.
The transport vesicle allows itself to be picked up by a transport protein and carried across the cell membrane.
As the transport vesicle approaches the cell membrane, a recognition marker opens the cell membrane. The lysosome then eats away a portion of the transport vesicle and the new protein leaks out of the cell into the interstitial fluid.
