Question	Answer
This membranous organelle contains oxidase and catalase enzymes.	peroxisome
In the matrix of the plasma membrane, a variety of proteins are embedded. Some of these proteins serve as passageway for Na+ ions or glucose. These proteins are called	transport proteins
Which type of junction is formed when membrane channels of adjacent plasma membranes adhere to each other?	gap junction
Ribosomes may be either free within the cytoplasm or bound to a membrane system known as the	rough endoplasmic reticulum.
Phospholipids of the plasma membrane are arranged	as a bilayer with their nonpolar tails sandwiched between the polar heads.
This organelle is characterized by folded membranes called cristae.	mitochondria
Which area of the cytoplasm near the nucleus coordinates the building and breaking of microtubules in the cell?	centrosome
This organelle is primarily a sac of powerful digestive enzymes called acid hydrolases.	lysosome
This organelle is numerous in liver and kidney cells	peroxisome
Ribosomes are organelles that	float in the cytoplasm and attach to the endoplasmic reticulum.
This membranous organelle is the site of protein synthesis for proteins that are secreted by the cell.	rough endoplasmic reticulum
The inside of the cell is composed largely of a gel-like substance called	cytoplasm.
A spherical membrane-bound structure that contains the genetic material of the cell and is often referred to as the “command center” of the cell is the	nucleus.
This organelle primarily modifies products from the rough ER, and it resembles a stack of hollow saucers, one cupped inside the next.	Golgi apparatus
This organelle has both a cis and a trans face.	Golgi apparatus
Which of the following is not a cytoskeleton element?	centriole
Which of the following cytoskeleton elements are the largest in diameter?	microtubules
Often referred to as the “power plant” of the cell, which organelle is the site of ATP production?	mitochondrion
Which of the following statements about integral proteins in the plasma membrane is false?	They are more abundant by volume than the membrane phospholipids.
A major function of the cell membrane is to	control what enters and leaves the cell.
Which of the following is a type of cell extension that lines the intestines and other areas of the body?	microvilli

Main cell structures include all of the following except:	interstitial fluid.
ATP production occurs within which organelle?	Mitochondrion
The enzyme catalase is an important chemical in the functioning of the	peroxisomes.
Lysosomes perform autophagy. This means that they: Correct!	break down proteins and cytoplasm that are not needed by “self eating.”
Which of the following is not a function of the integral membrane proteins?	Acting as receptors.....Signal transduction .....Identification of “self”
The identification function of the cell membrane is carried out by the:	glycoprotein molecules
The cell extension that contains microfilaments is called:	microvilli.
DNA is a major constituent of which cell organelle?	Nucleus
