Honors Biology, Semester 1 exam review

Process that requires oxygen

Composed of long chains of one or more amino acids

Posotively charged

Cell organelle consisting of RNA and protein found throughout the cytoplasm in a cell

Organic compounds found in food, such as sugars

Happens in the Calvin cycle and converts CO2 into glucose

an optical instrument used for viewing very small objects.

She comparing two soloutions, the soloution with lesse concentration of solutes

of or relating to the poles of a cell, organ, or part

What is NOT a characteristic of life

a network of membranous tubules within the cytoplasm of a eukaryotic cell

the basic unit of a chemical element

Diffusion of water through a selectively permeable membrane

the sticking together of particles of the same substance

Substances that cannot be broken down into simpler substances

Thin, flexible barrier that surrounds all cells; regulates what enters and leaves the cell

the group in an experiment that receives the variable being tested

Process of diffusion in which molecules pass across the membrane through cell membrane channels

Negatively charged

Molecules that consist on long chains of nucleotides

not "true fats" because they have one of the fatty acids replaced by a phosphate group

Positive, negative, and none are types of what

Explanation that explains observations and hypotheses

a cell transports molecules into the cell by engulfing them in an energy-using process

A measure of acidity or basicnes of water soluble substances

the study of living organisms

Process of noticing and describing events or processes in a careful, orderly way

movement of biochemicals across cell membranes without need of energy input.

What type of cell is this

Values below 7 on the Ph scale

the sticking together of particles of different substances

An organism with a nucleus

a region on an enzyme that binds to a protein or other substance during a reaction

a type of bond that occurs when two atoms share a pair of electrons with each other

Strong, supporting layer around the cell membrane in some cells

What is Adenosine Triphosphate

the complete transfer of valence electron(s) between atoms

a substance produced by a living organism that acts as a catalyst

Used in photosynthesis and combines with water to make glucose

A very large molecule

a process in which an intracellular vesicle moves to the plasma membrane

a variable whose value depends on that of another

Above 7 on the Ph scale

a substance produced during a natural, chemical, or manufacturing process.

a region on an enzyme that binds to a protein or other substance during a reaction

a chemical bond that involves the sharing of electron pairs between atoms

When comparing two soloutions, the solutions with the greater concentration of soloutes

a substance that takes part in and undergoes change during a reaction

The center of an atom

Long strands of fatty acids

Process by which particles tend to move from an are of high concentration to low concentration

An organism with no nucleus

sugar that is an important energy source in living organisms

organelle that captures energy from the sun and converts it into chemical energy

Takes place in the thylakoids membranes during photosynthesis

the movement across a cell membrane into a region of higher concentration, requiring energy.

The powerhouse of the cell

When a concentration of two soloutions are the same

proteins involved in the movement of ions, small molecules, or macromolecules

No charge

What is this

the group in an experiment or study that does not receive treatment by the researchers

Used in photosynthesis and combines with CO2 to make glucose

What type of cell is this
