Question 1 - 10

• The light reactions are directly dependent on this. Organisms that undergo chemosynthesis

do not require this.

Answer 1 – 10

• sunlight

Question 1 - 20

• The light reactions take place in this part of the plant cell (be specific).

Answer 1 – 20

• Thylakoid membrane

Question 1 - 30

• Water molecules are needed for what reason?

Answer 1 – 30

• Hydrogen proton gradient drives synthesis of ATP.

Question 1 - 40

• This molecule is found inside the photosystems and is responsible for capturing light.

Answer 1 – 40

• Pigments (Chlorophyll A and B)

Question 1 - 50

• Primary electron receptors are reduced as electrons are passed along in the light dependent reactions. This movement of electrons from PSII to PSI is called what?

Answer 1 – 50

• Electron transport chain

Question 2 - 10The Calvin Cycle requires these molecules from the light dependent reactions.

Answer 2 – 10

• ATP and NADPH

Question 2 - 20

• The Calvin Cycle can only occur during the day. true or false?

Answer 2 – 20

• false

Question 2 - 30

• The molecule that acts as a precursor to glucose in the Calvin Cycle has how many Carbon atoms?

Answer 2 – 30

• three

Question 2 - 40

• The Calvin Cycle must go through how many “spins” before it creates 1 molecule of glucose?

Answer 2 – 40

• six

Question 2 - 50

• Crabgrass, a C4 plant suitable for hot, dry environments, keep these structures closed during the day to prevent water loss. The downside is during this time they can’t take in CO2 for the Calvin Cycle.

Answer 2 – 50

• stomata

Question 3 - 10

• The chemical formula for photosynthesis is this.

Answer 3 – 10

• 6CO2 + 6H20 C6H1206 + 6O2

Question 3 - 20

• The overall goal of photosynthesis is to use solar energy to produce what?

Answer 3 – 20

• glucose

Question 3 - 30

• The three factors that affect photosynthesis are:

Answer 3 – 30

• Temperature• Light intensity• CO2 levels

Question 3 - 40

• A stack of thylakoids is referred to as this.

Answer 3 – 40

• granum

Question 3 - 50

• Specifically, where do the light dependent and independent reactions take place inside the cloroplast?

Answer 3 – 50

• Thylakoid membrane and stroma

Question 4 - 10

• These separate the inside and outside of chloroplast and thylakoid by building a membrane.

Answer 4 – 10

• Phospholipid bilayer

Question 4 - 20

• What are the names of the chlorophyll containing proteins embedded in the thylakoid membrane?

Answer 4 – 20

• Photosystem II and photosystem I

Question 4 - 30

• The name of the protein that is responsible for creating ATP from ADP plus phosphate in the light dependent reactions is this.

Answer 4 – 30

• ATP synthase

Question 4 - 40

• Hydrogen protons are pumped into the interior of the thylakoid to create this which helps drives the synthesis of ATP.

Answer 4 – 40

• Concentration gradient

Question 4 - 50

• The light dependent reactions take place across a series of proteins embedded in the thylakoid membrane. ATP and NADPH never cross this membrane but are instead created here, the site of the Calvin Cycle.

Answer 4 – 50

• stroma

Question 5 - 10

• Facilitated diffusion does or does not require energy?

Answer 5 – 10

• Does not require energy

Question 5 - 20

• The sodium potassium pump is an example of active transport which means that it does or does not require energy?

Answer 5 – 20

• Does require energy (ATP)

Question 5 - 30

• This is the process by which cells use vacuoles to transport molecules outside of the cell.

Answer 5 – 30

• exocytosis

Question 5 - 40

• Molecules can be stockpiled inside a cell, against the concentration gradient, by using this process.

Answer 5 – 40

• Active transport

– Ex: sodium potassium pump

Question 5 - 50

• An amoeba can ingest substances (often times its prey) through this process.

Answer 5 – 50

• Phagocytosis a specific kind of endocytosis

• Our bodies use phagocytes to engulf and break down bacteria during an infection.
