• Leaf

• Thylakoid

Where is oxygen released in the Light Dependent Reaction

• chloroplast

• thylakoid

• cytoplasm

• stroma

What makes ATP into ADP?

• Take away 3 phosphate groups

• Take away a single phosphate

• Nothing, simply keep all the phosphate

• Add a phosphate

What two carrier molecules are required as input for dark reactions to take place?

• ADP

• NADP+

• ATP

• NADPH

Which structures make up a molecule of ATP

• Hydrogen base, ribose, and 2 phosphate groups

• Nitrogen base, ribose, and 3 phosphate groups

• Nitrogen base, glucose, and 3 phosphate groups

What is the equation for photosynthesis?

(a)  

Why do organisms need ATP

• To create a food source

• To allow themselves to grow

• To provide energy to carry out processes

What is chemo-synthesis?

• A process in which organisms make food with chemical energy

• A process in which bacteria make food with chemical energy

• A process in which chemical energy is stored in the chloroplast and used during photosynthesis

• A process in which chemical energy turns into light energy

Name two high energy molecules in the diagram above used as an energy carrier

(a)  

If carbon dioxide is removed from a plant's environment, what would you expect to happen to its production of high energy sugars?

• production would increase

• production would decrease

• production will stay the same

Answer explanation

There would be less production since carbon dioxide is needed to make glucose
