Which statement about ATP is correct?
The molecule ADP contains stored energy. When the phosphate molecule is removed the energy is released.
The molecule ADP contains stored energy. When the phosphate molecule is removed the energy is stored.
The molecule of ATP contains stored energy. When the phosphate molecule is removed the energy is released.
The molecule of ADP is like a fully charged battery. It releases energy when the phosphate molecule is broken.

How are cellular respiration and photosynthesis related to each other?
Photosynthesis uses carbon dioxide and water to make sugar and oxygen; which are then the reactants for cellular respiration.
Cellular respiration uses carbon dioxide and water to make sugar and oxygen; which are then the reactants for cellular respiration.
Cellular Respiration uses carbon dioxide and water to make sugar and oxygen; which are then the reactants for photosynthesis.
Photosynthesis uses carbon dioxide and water to make sugar and oxygen; which are then the reactants for photosynthesis.
Select all the statements that are true.
What is produced in photosynthesis is used in cellular respiration
Radiant energy is converted into ADP
Radiant energy is converted and stored in glucose molecules
Cellular respiration converts glucose into ATP
How are cellular respiration and photosynthesis related?
The product of CR is CO2 which photosynthesis will use.
The product of CR is CO2 which Cellular Respiration will use.
The product of photosynthesis CO2 will be used by CR.
The product of photosythesis CO2 will be used by photosynthesis.
When placing dialysis tubing in a beaker with a high concentration of toxins will the toxins go inside the bag or out of the bag and why?
The toxins will move into the bag because of diffusion. Moving from high to low.
The toxins will move out of the bag because of active transport
The solutions will remain the same because the solution is isotonic
The toxins will move into the bag because of osmosis. The water is moving from high to low.
This is the ATP molecule. What are the 3 Parts of this molecule?
Adenosine
Ribose

Why do plants need both Mitochondria and Chloroplast?
Mitochondria makes the sugars needed for the chloroplasts to make ATP
Plants do not have mitochondria
Plants need the chloroplasts to make the sugars and then need the mitochondria to break down the sugar for cell energy.
Plants do not have chloroplasts
Which macromolecule do we eat that is needed to make ATP in the mitochondria?
lipids
nucleic acid
proteins
carbohydrates
What must happen to this molecule to use the energy necessary to run a marathon?
Break all the phosphates off to use the energy in the phosphate molecule.
Break the last phosphate to release the energy locked in the bond
Add another phosphate; the more phosphate you have the more energy you have.
break the ribose sugar up into little pieces so we can use it to make to energy.
ATP is used and it becomes ADP. The cell will...
discard it as waste by diffusion
discard it as waste by exocytosis
Add the phosphate back to ADP to make it ATP again.
Break another phosphate molecule to get more energy.
