These elements have high melting points and densities. They are located in group 1A and 11A.
What is Metals
100
Two or more reactants form one product.
What is a combination reaction
100
Also known as sugars, they have important roles in energy and metabolism and storage, and structure of the cell and organisms.
What are carbohydrates
100
bacteria and cyanobacteria. unicellular organisms with a simple cell structure. outer lipid bilayer cell membrane. Have no true nucleus and genetic material consists of a single molecule of DNA
What prokaryotic cells
100
Uniport proteins carry a single solute across the membrane. Symport proteins translocate two different solutes simultaneously in the same direction. transport occurs only if both solutes bind to the proteins.
What transport proteins
200
These elements are brittle in a solid state and show little to no metallic luster. They have high ionization energies and electro negativities.
What are non metals
200
One in which a compound breaks down into two or more substances. Result of heating
What is a decomposition reaction
200
Play a important role in energy metabolism and cellular membranes. Composed of carbon, hydrogen and oxygen. Have much lower oxygen content than carbohydrates and are less oxidated.
What are lipids
200
enclosed within a lipid bilayer cell membrane. Contain organelles, membrane bound structures within the cell with specific functions isolated in separate compartments
What are eukaryotic cells
200
net movement of dissolved particles down their concentration gradients. From a region of higher concentrantion to a region of lower concentrantion
What is diffusion or passive transport
300
These elements are in group 1A. They have densities that are lower than other metals. They have one loosely bound electron in their outermost shell.
What are alkali metals
300
An atom of one compound is replaced by an atom of another element.
What is a single displacement reaction
300
Act as biological catalysts to speed up chemical reactions
What are enzymes
300
an important component of cellular structure. Encloses the cell and exhibits selective permeability. Regulates the passage of materials into and out of the cell.
What is the plasma membrane
300
net movement of dissolved particles down their concentration gradient with the help of carrier proteins
What is facilitated diffusion
400
These elements are in group 11A. Their properties are dependent upon the ease with which they lose electrons. They have two electrons in their outer shell and have smaller atomic radii thn the alkali metals
What are alkaline earth metals
400
elements from two different compounds displace each other to form two new compounds
What is a double displacement reaction
400
polymers formed by joining sample building blocks to carry our a broad range of functions
What are proteins
400
nucleus, endoplasmic reticulum, Golgi apparatus....Regulate and partition the flow of material into and out of thee compartments
What are organelles
400
net movement of dissolved particles against their concentration gradient with help of transport proteins. requires external energy.
What is active transport.
500
These are sometimes called inert gases. They are found in group VII. They are non reactive and have complete valence shell. Have low boiling points and are all gases at room temperature.
What are nobel gases
500
A specific type of displacement reaction that occurs when an acid reacts with a base to produce a solution of a salt and water.
What is neutralization reaction.
500
found in all living organisms acting as informational molecules. polymers formed by joining together specific monomers called nucleotides.
What are nucleic acids
500
largest organelles of the cell. site where gene are read to produce messenger RNA. Surrounded by a two layer nuclear membrane that maintains a nuclear environment distinct from that of the cytoplasm.
What is the nucleus
500
simple diffusion of water from a region of lower solute concentration to a region of higher solute concentration
