Building Blocks of Biomolecules
Contain carbon, hydrogen and oxygen, they are hydrophobic and used in making the cell membrane
lipids
True or False: Reactants are written on the right side of the chemical equation and Products are written on the left side of the chemical equation.
False
What part of the cell serves to process, package and export proteins
Golgi Aparatus
Type of transport in which water passes from a less concentrated salt solution to a more concentrated salt solution.
Osmosis
___________ 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
Large numbers of ribosomes exit in what part of the cell and what do they do?
Rough ER and synthesize proteins
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
carbohydrates
Chemical reactions that absorb more energy than they release
Endothermic
Which organelle synthesizes phospholipids for the cell membrane
smooth ER
A molecule that crosses the cell membrane binds to what type of molecule inside the membrane?
Membrane Receptor
True or False: Active transport moves molecules from low concentration to high concentration.
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.
ATP
which of the following has the highest amount of H+ atoms

pH =1
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
