UNIT 2

Phosphate Flip-Flop

100

This molecule is known as the "energy currency" of the cell.

ATP

200

What are the 3 pieces of an ATP molecule?

Adenine, ribose sugar, phosphate group.

300

When ATP loses a phosphate group, it becomes this lower-energy molecule.

ADP

400

This bond is broken when ATP releases energy for fcellular work.

High-energy phosphate bond (or the bond between the second and third phosphate).

500

This cellular process in the mitochondria regenerates ATP from ADP using energy from glucose.

Cellular Respiration

Sun's out, Sugars out

100

This organelle is where photosynthesis takes place in plant cells.

Chloroplast

200

This green pigment absorbs light for photosynthesis.

Chlorophyll (thylakoid)

300

These are the three reactants needed for photosynthesis:

CO2, H2O, Light Energy

400

This stage of photosynthesis occurs in the thylakoid and produces ATP and NADPH. Waste product is O2.

Light-dependent reactions.

500

During the calvin cycle, this molecule from the light-dependent reaction provides energy needed to build glucose.

ATP

Party at the Powerhouse

100

This organelle is the site of cellular respiration.

Mitochondria

200

This gas is required to accept electrons in cellular respiration. 

O2

300

This first stage of cellular respiration occurs in the cytoplasm and breaks glucose into molecules of pyruvate.

Glycolysis

400

This stage of cellular respiration produces the most ATP:

The electron transport chain

500

If oxygen is not available, cells switch to this anaerobic process so that glycolysis can continue:

Fermentation

You are what you eat

100

These are the four major types of biological macromolecules found in living things:

Carbs, lipids, proteins, nucleic acids

200

This macromolecule is the main source of quick energy for cells.

Carbs

300

What are the building blocks for proteins?

Amino acids

400

What are the building blocks of nucleic acids?

Nucleotides

500

What are the building blocks for lipids?

Fatty acids

What's the Formula?

100

This gas is a reactant in photosynthesis and a product of cellular respiration.

CO2

200

This gas is a product of photosynthesis and a reactant of cellular respiration

O2

300

This molecule (C6H12O6) is produced in photosynthesis and broken down during respiration

Glucose

400

What cellular process uses this equation:

6CO2 + 6H2O + Energy ---> C6H12O6 + 6O2

Photosynthesis 

500

What is the missing piece of this reaction notated by "X"?

O2 + C6H12O6 ---> CO2 + X + ATP 

H2O
