100

An element is defined by this number.

Atomic number, number of protons

100

These compounds largely consist of carbon along with hydrogen, nitrogen, and oxygen, and form the basis for all life.

Organic

100

This fatty acid contains the maximum number of hydrogens

Saturated fatty acid

100

The four levels of protein structure: sequence, local arrangements, overall folding, and multiple chains together.

Primary, secondary, tertiary, quaternary

100

The process by which sunlight is converted into chemical energy, and the process of breaking down organic material for energy.

Photosynthesis

200

The smallest unit of matter that still retains chemical properties.

Atom

200

A substance composed of multiple elements.

Compound

200

Sugar molecules used for short-term energy

Carbohydrate, saccharide

200

These molecules perform all the major functions in the cell.

Proteins

200

A system of organisms interacting with their environment.

Ecosystem

300

These three particles make up an atom: one positive, one negative, and one neutral.

Proton, electron, neutron

300

This type of bond involves the mutual sharing of electrons.

Covalent

300

A chain of many sugar molecules

Polysaccharide

300

The basic unit of a protein.

Amino acid

300

Nonliving components of an ecosystem.

Abiotic factors

400

The positively charged core of an atom, made of protons and neutrons.

Nucleus

400

The process that transforms substances by rearranging atoms and their bonds.

Chemical reaction

400

Long chains of carbons used for long-term energy storage.

Lipid, fat

400

DNA has this structure

Double helix

400

Organisms that convert abiotic energy into food.

Autotroph

500

This version of an element has a different number of neutrons.

Isotope
500

This type of bond is an electrical attraction between oppositely charged atoms and can be thought of as a transfer of electrons.

Ionic

500

Three fatty acids bonded to a glycerol molecule

Triglyceride

500

DNA has A-T and C-G pairs; this single-stranded molecule pairs A with U.

RNA (Ribonucleic acid)

500

Energy cannot be created or destroyed
