___________ is a process that takes substances into the cell
Endocytosis
held together by peptide bonds, used to make proteins
amino acids
Proteins that convert reactants to products by making a chemical reaction go faster.
Enzyme

True or False: diffusion moves molecules to an area of lower concentration.
False
______________ is a process that releases substance outside the cell
Exocytosis
short term energy molecule, cellulose and starch are examples of these

Chemical reactions that absorb more energy than they release
Endothermic

True
nucleotides
Activation energy needed for a chemical reaction is decreased by a
Catalyst
Which organelle is involved in the production of energy molecules for the cell
mitochondria
A molecule that sends a messsage to the cell by binding to which type of molecule in the cytoplasm or inside of the cell.
Intercellular Receptor
The energy molecule that provides energy for active transport.

Given that cells are the basic unit of life and that all living things are made up of cells, what is the third principle of Cell Theory
All cells are produced from existing cells
which organelles are involved in the process of endocytosis
The vacuole will (Absorb/release) water when a cell is put into a higher salt concentration compared to its own contents.
Release - water is flowing out of the cell
True or False: Endocytosis and Exocytosis require energy and are an example of active transport.
True
