$200

What is radiant energy and chemical energy?

These two forms of energy explain two of the most

important energy transformations that occur in

biological systems.

$400

What is metabolism?

These are all of the chemical reactions that take place in an

organism.

$600

What is the reactants are 4 Fe and 3 O2 and the product is 2 Fe2O3?

These are the reactants and products of the following

chemical reaction.4 Fe + 3 O2      2 Fe2O3

$800

What is the activation energy?

This is the little (or big) push of energy needed to get a chemical reaction going.

$1000

What is an enzyme?

A type of protein or RNA molecule found in a living

thing that speeds up metabolic reactions without being used up or destroyed.

$200

What is hydrogen bonding?

This is the type of bonding that water molecules have due to their bond

polarity. It allows water to be cohesive, be adhesive, have a high heat capacity,

and dissolve many other substances.

$400

What is a solute?

The substance that gets dissolved in a solution.

$600

What is water?

This substance is considered the universal solvent because most things (polar substances) will

dissolve in it.

$800

What is cohesion and surface tension?

These properties of water allows water to travel from root to leaves in a plant and

some insects to walk on water.

$1000

What is less?

Hydrogen bonding allows the density of solid ice to be ________ than that of its

liquid form.

$200

What are bases?

The term alkalinity refers to these.

$400

What is pH?

It literally means “potential hydrogen.”

$600

What is an acid?

The properties include: gives off H+ in solution, tastes sour, can be corrosive to

metals, and turn blue litmus red.

$800

What is gives off OH- ions in solution, taste bitter, and turns red litmus blue?

These are three properties of a basic substance.

$1000

What are buffers?

Our bodies have these specific types of chemicals that maintain homeostasis in terms of pH by neutralizing acids and bases.

$200

What are organic compounds?

Compounds that are primarily made of carbon.

$400

What is a monomer?

A simple molecule that can combine with other

molecules to build bigger molecules.

$600

What are polymers?

The GAK and slime that we made last year are examples of these and gummy bears

too.

$800

What are macromolecules?

A very large organic compound composed of hundreds or thousands

of atoms. They include carbohydrates, proteins, lipids, and

nucleic acids.

This monomer unit of a protein that is composed of carbon, hydrogen, oxygen,

and nitrogen. They are the building blocks of proteins.

$600

What is a polysaccharide?

A type of complex sugar (carb) that is composed of three or more monosaccharides. An

example is glycogen.

$800

What are lipids?

Examples of this type of macromolecule include

triglycerides, phospholipids, waxes, and steroids.

$1000

What is DNA is a double helix whereas RNA is only single stranded?
