What could be considered a symptom of disease?
ANSWERS: anxiety
The disaccharide sucrose can be broken down to form the monosaccharide glucos and fructose in a
process called
ANSWERS: hydrolysis
Glycogen, a polysaccharide, contains many unstable carbon-hydrogen bonds and is readily oxidized.
Glycogen is thus very effective as a
ANSWERS: an energy storage molecule
Enzymes are a subclass of proteins that
ANSWERS: catalyze chemical reactions by lowering the required activation energy
The quaternary structure of a protein
ANSWERS: results from an arrangement of multiple polypeptide chains
The high thermal stability of water is a result of
ANSWERS: hydrogen bonding between water molecules
What describes the bonds that attach the hydrogen atoms to the oxygen atom in the water molecule?
ANSWERS: The are polar bonds and they are hydrogen bonds
allows binding of chemical messengers
ANSWERS: receptor
What is a function of proteins?
ANSWERS: catalyzing chemical reactions
ATP funcions as an

abundance of
ANSWERS: cilia
The plasma membrane includes proteins with short carbohydrate chains attached. These are called
ANSWERS: glycoproteins
Is epithelium vascular?
ANSWERS: no
Alternative splicing refers to
ANSWERS: the way in which a single gene can code for several different polypeptides
The cellular process of translation occurs where
ANSWERS: at the ribosomes of the cell
What are four functions of connective tissue?
ANSWERS: binding together other tissues; transporting materials around the body; storing energy
reserves; protecting internal organs
The alveoli of the lungs, where gas exchange occurs, are lined with simple squamous epithelial tissue
because
ANSWERS: a thin surface facilitates diffusion
What is an extension from the soma of a neuron that receives incoming signals?
ANSWERS: dendrite
Tissue regeneration occurs
