Terms in this set (58)
The process of moving substances into cells or across tissues.
The building block of a protein. There are 23 different types, each with a different side chain.
A set of processes which build large molecules from smaller, building block molecules.
A molecule that holds useful chemical energy; the energy currency molecule.
Molecules made and found only in living organisms.
A biomolecule made entirely from carbon, hydrogen, and oxygen in a 1:2:1 ratio. Mostly utilized for quick energy.
Set of metabolic processes which break down large molecules into smaller, building block molecules.
The repetitive growth and division of a cell and described in phases; starting with interphase and followed by prophase, metaphase, anaphase, telophase, and cytokinesis.
A phospholipid bilayer which controls the movement of substances in and out of the cell.
A tough structural layer made of cellulose that surrounds plant cells.
The aerobic process of breaking down carbohydrates for energy in the form of ATP. The chemical equation for this process is: C6H12O6 + 6O2 ---> 6CO2 + 6H2O
The force of attraction between atoms in a molecule.
A way of expressing the proportion and number of all atoms in a molecule.
A process that rearranges atoms into different molecules.
A green pigment which absorbs light during photosynthesis.
The organelle that performs photosynthesis.
The threadlike structure formed from one molecule of DNA.
CHNOPS (carbon, hydrogen, oxygen, phosphorous, and sulfur)
The six most common elements found in living things.
Two or more different elements bonded together.
Two or atoms bonded together.
An experimental treatment that will produce a known effect.
An experimental treatment that is known to NOT produce an effect.
The part of the cell division processes where the cytoplasm of a single parent cell divides into two daughter cells.
The material within a living cell including the cytosol and the organelles.
The process of breaking down food by mechanical and chemical action.
All atoms with the same properties and number of protons.
The smallest unit of matter that shares properties of its element.
Radiant light from the sun that is captured by plants during photosynthesis.
Energy stored in the bonds between atoms of a molecule.
A type of protein that catalyzes chemical reactions.
An organism whose cells contain membrane-bound organelles and genetic material contained within a nuclear membrane.
A response to a stimulus which causes a change opposite of the stimulus, moving the system back toward homeostasis.
A response to a stimulus which causes a change that increases the same stimulus, pushing the system away from homeostasis.
The process of breaking down carbohydrates for energy without the presence of oxygen. Produces either lactic acid or alcohol as a waste by-product.
A type of sugar that is an important energy source for living things. It has the chemical formula C6H12O6.
The group in an experiment that is exposed to the variable being studied.
The group in an experiment that is NOT exposed to the variable being studied.
The ability of an organism to maintain a stable internal environment.
Having the tendency to be water-loving. Will mix with water.
Having the tendency to be water-hating. Does NOT mix with water.
A solution used to test for the presence of certain molecules or conditions in a solution.
The first and longest phase of the cell cycle.
A type of biomolecule made entirely of carbon, hydrogen, and oxygen. Used for long-term energy storage, cell membranes, and insulation.
All chemical processes that occur within a living organism to maintain life.
The powerhouse of the cell; where aerobic cellular respiration occurs.
A type of cell division that produces two genetically identical daughter cells.
A large biomolecule made from a repeating chain of nucleotides.
Where all the genetic information of a cell is stored.
A substance organisms require in order to carry out life's processes.
A chemical process that stores solar energy as chemical energy. The chemical equation for the reaction is: 6CO2 + 6H2O ---> C6H12O6 + 6O2

Where proteins are made in a cell.
A very large molecule resulting from a long chain of glucose molecules.
A variable in an experiment that is intentionally changed or controlled. Typically graphed on the x-axis.
A variable in an experiment that is measured and affected by the experiment. Typically graphed on the y-axis.
A variable in an experiment that is unchanged or held constant during the experiment.
