NSG214 (Cells) Latest Update Questions &
Answers Verified 100% Correct!
What is homeostasis?
The ability to respond to and maintain physiologic and psychological stability during rapidly
changing conditions in the internal and external environments
What is Pathophysiology?
The study of the structural and functional characteristics in the cell, tissues, and organs of the
body that cause or are caused by disease
What is a cell?
The smallest functional unit in the body
What are the components of a cell?
cell membrane, cytoplasm, nucleus
What is the function of the cell membrane?
It is a semi-permeable boundary which controls what goes in and out of the cell. It is is made up
of a lipid bilayer. Selectively permeable to maintain homeostasis in cell.
What substances have free passages into the cell membrane?
enzymes, glucose, and electrolytes.
What does the nucleus of a cell contain?
RNA and DNA (genetic material)
, What occurs in the nucleus?
Protein synthesis (transcription and translation which form polypeptide chains). Regulates cell
(reproduction, growth, metabolism)
What substances does the cytoplasm contain?
Water, nutrients, ions, gas, and waste.
What organelles (other than the nucleus) does the cytoplasm contain?
ribosomes, Golgi apparatus, and mitochondria
What is Aerobic metabolism (Kreb's cycle)?
Oxygen based. Provide mitochondria with oxygen necessary to metabolize fats, proteins, and
carbohydrates. CHO first, triglycerides second
When does cellular metabolism begin?
When food enters GI tract
What is anaerobic metabolism?
Glucose-based. Uses glycolysis for temporary energy when O2 supply is diminished. End
production is lactic acid. Glucose to ATP
What occurs if there is too much lactic acid (too much anaerobic metabolism)?
Muscle spasms, fatigue, pain, MA, respiratory failure, kidney failure, and death.
What is the proliferation of cells controlled by?
by genes and proteins which stimulate or supress
