BIO 201 EXAM 1 QUESTIONS AND
ANSWERS
What is gross anatomy - answer- ...branch of anatomy that deals with the structure
of organs and tissues that are visible to the naked eye.
Define embryology, cytology & microscopic anatomy - answer- ...Embryology-
development before birth, Cytology- cells of the body, Microscopic Anatomy-
structures to small to be seen with naked eye
The main component of the cytoplasm - answer- ...Cytosol
What is mitosis - answer- ...cell division that results in two daughter cells each
having the same # and kind of chromosomes as the parent nucleus, typical of
ordinary tissue growth.
Role of leptin in the body - answer- ...Leptin regulates energy intake and fat stores
so that weight is maintained within a relatively narrow range. "Leptin is a hormone
made by fat cells, that decrease appetite"
What is an organic molecule - answer- ...are the molecules of life and are built
around chains of carbon atoms that are often quite long.
Some functions of lysosomes - answer- ...they breakdown, degrade and digest
safely within a cell
What type of epithelium would you find dense microvilli( lining intestines and kidney
tubules) - answer- ... simple cubodoidal epithelium
Where would you find Pseudostratified columnar epithelia - answer- ...ciliated is
found in the trachea and upper respitory tract; non ciliated is found in the male sperm
Major functions of fat - answer- ...provides reserve fuel for cell, insulates against heat
loss, supports and protects organs
What is metabolism - answer- ... either Anabolism- which build larger molucules from
smaller ones ( storage of energy). Catabolism- which breaks down from complex
molecules to simpler ones ( with the release of energy).
What do collagen fibers do for IVDs ( intervertebral discs) - answer- ...they provide
strentgh with there crosslinks which resits being pulled apart, as well as cushoining.
What produces the most ATPs during cellular respiration - answer- ...glucose, and
the electron transport chain
What is a frontal section/cut - answer- ...through torso- divides the body by
anterior(front) and posterior(back)
, Improperly digesting nutrients, may indicate a problem of which tissue layer -
answer- ...simple epithelium
When does the body normally use proteins for energy (ATP) - answer- ...When the
body is in starvation mode( doesnt have enough carbohydrate or fat calories for Atp
production.
Normal constituents of the plasma membrane - answer- ...seperates the inracellular
fluid wihin the cell and the extracellular fluid outside the cell.
What are endocrine glands - answer- ductless glands - secrete hormones directly
into blood or lymph ex. pituitary, thyroid
What is phagocytosis - answer- ...cell eat- ingestion of bacteria or other material
The primary function of cellular respiration - answer- ...metabolism to form ATP
The basic structural material of the body is made of what - answer- ...Proteins
What are microvilli - answer- ...projections from the surface of some cells, have a
fuzzy appreance called a brush border (fingerlike extensions)
What is passive membrane transport; - answer- ...substances cross the membrane
without any energy input from the cell; unlike active transport that requires energy
from the cell
What are the characteristics of Psuedostratified Columnar Epithelium -
answer- ...single layer of cells of differing heights, some not reaching the free
surface; nuclei seen at diffrent levels; may contain mucus secreating cells and bear
cilia.
What is basal metabolic rate (BMR) - answer- ...reflects the energy the body needs
to perform only its most essential activities. ( this happens at an in rest state ;
neutral)
What is Simple Squamous Epithelial tissue - answer- ...one layer, flat egg shaped ,
allows materials to pass by diffusion and filteration in sites where protection is not
important; secretes lubricating substances in serosae;
Why should elderly patients decrease their caloric intake - answer- ...becasue their
BMR reduces dramaticly, if they increse their calorie intake they will gain weight
The functions of tRNA - answer- ...carry amino acids to the ribosomes, there they
decode mRNA's msg for amino acid sequence in the polypeptide to be built
Salts are ALWAYS _______ - answer- ...ionic compound
Which tissue is highly cellular and vascularized - answer- ...muscle tissue
