2 Applied Pathophysiology for the Advanced Practice Nurse 1st Edition Dlugasch Story Test Bank Chapter 1 Cellular Function

• Although energy is not made in mitochondria, they are known as the power

plants of the cell because they:

• contain RNA for protein synthesis.
• utilize glycolysis for oxidative energy.
• extract energy from organic compounds.
• store calcium bonds for muscle contractions.

• Although the basic structure of the cell plasma membrane is formed by a

lipid bilayer, most of the specific membrane functions are carried out by:

• bound and transmembrane proteins.
• complex, long carbohydrate chains.
• surface antigens and hormone receptors.
• a gating system of selective ion channels.

• The nucleus , which is essential for function and survival of the

cell.

• is the site of protein synthesis
• contains the genetic code
• transforms cellular energy
• initiates aerobic metabolism 2 / 4

• To effectively relay signals, cell-to-cell communication utilizes chemical

messenger systems that:

• displace surface receptor proteins. 3 / 4

• accumulate within cell gap junctions.
• bind to contractile microfilaments.
• release secretions into extracellular fluid.

• Exocytosis, the reverse of endocytosis, is important in into the

extracellular fluid.

• Engulfing and ingesting fluid and proteins for transport
• Killing, degrading, and dissolving harmful microorganisms
• Removing cellular debris and releasing synthesized substances
• Destruction of particles by lysosomal enzymes for secretion

• The process responsible for generating and conducting membrane potentials

is:

• diffusion of current-carrying ions.
• millivoltage of electrical potential.
• polarization of charged particles.
• ion channel neurotransmission.

• Epithelial tissues are classified according to the shape of the cells and the

number of layers. Which of the following is a correctly matched description and type of epithelial tissue?

A) Simple epithelium: cells in contact with intercellular matrix; some do not

extend to surface

• Aerobic metabolism, also known as oxidative metabolism, provides energy

by:

• removing the phosphate bonds from ATP.
• combining hydrogen and oxygen to form water.
• activating pyruvate stored in the cytoplasm.
• breaking down glucose to form lactic acid.
