Unit 4 test

How is energy released through an ATP molecule, what must happen?

You have to break the bonds.

Where is the energy located in the ATP molecules

Bonds

How many phosphate groups does ADP have.

2

How many phosphate groups does ATP have.

3

What are pigments?

Light absorbent molecules.

What is the first step to photosynthesis, what needs to be absorbed?

Sunlight through chloroplast is the first step.

What is split during light dependent reaction of photosynthesis.

Water molecules.

Where does the Calvin Cycle/ light independent reaction take place.

in the stroma of chloroplast

What is the input/reactants of photosynthesis

Sun energy, water, carbon.

What are the outputs/products of photosynthesis

Oxygen

In photosynthesis is sunlight a reactant or product.

Reactant

Where does photosynthesis occur.

Chloroplast

What is a synonym for heterotroph.

Hunter/predator

Carbon dioxide gets into plant cells through the

stroma

Where does cellular respiration occur.

Mitochondria

What are the main three steps of cellular respiration?

Krebs cycle, glycolysis, etc (electrons transport chain)

What does glucose get broken down into?

Carbon dioxide, water.

If cellular respiration does not use oxygen what pathway will it follow?

Fermentative, Anaerobic

Aerobic respiration requires

oxygen

Anaerobic respiration does not require

oxygen

What is metabolism?

The speed of breaking down food.

What is the inputs/reactants of cellular respiration.

oxygen, sugar.

What are the outputs/products of cellular respiration.

water

What does respiration remove from the atmosphere

oxygen

What does respiration release into the atmosphere

carbon

Where does glycolysis occur?

Cytoplasm

Where is the cytoplasm

Outside mitochondria

When you feel a burning sensation in your muscles after sprinting this is due to

homeostasis

What is the best way to describe the relationship between photosynthesis and cellular respiration

Photosynthesis makes glucose that cellular respiration uses to make ATP.

Oxygen is given off

photosynthesis

Pyruvate is produced

Cellular respiration

Sunlight is required

Photosynthesis

Water is formed

Cellular respiration

Includes Calvin cycle

photosynthesis

Carbon dioxide is taken in

photosynthesis

Food is broken down

Cellular respiration

Occurs in plants
