Flashcards in Chapter 3 Deck (15):
Energy-requiring process in which transports proteins bind with particles and move them through a cell membrane.
A type of passive transport in cells in which molecules move from areas where there are fewer of them.
Process by which a cell takes in a substance by surrounding it with the cell membrane.
A type of protein that regulates nearly all chemical reactions in the body without being changed or used up itself.
Occurs when molecules of one substance are spread evenly throughout another substance.
Process by which vesicles release their contents outside the cell.
Process by which oxygen-lacking celled organisms release small amounts of energy from glucose molecules and produce wastes such as alcohol, carbon dioxide, lactic acid.
Compound, such as H2O, that is made from elements other than carbon and whose atoms usually can be arranged
in only one structure.
The total of all chemical reactions in an organism.
A combination of substances in which the individual substances do not change or combine chemically but instead retain their own individual properties; can be gases, liquids, or any combination of them.
Compounds that always contain hydrogen and carbon; carbohydrates, liquid, proteins, and nucleic acids are organic compounds found in living things.
A type of passive transport that occurs when water diffuses through a cell membrane.
Movement of substances through a cell membrane without the use of cellular energy; includes diffusion, osmosis, and facilitated diffusion.
Process by which plants and many other producers use light energy to produce a simple sugar from carbon dioxide and water and give off oxygen.
