BIO 201 EXAM 1QUESTIONS AND ACCUARATE ANSWERS 2024/2025 | VERIFIED
What is gross anatomy - ...branch of anatomy that deals with the structure of organs and tissues
that are visible to the naked eye.
Define embryology, cytology & microscopic anatomy - ...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 - ...Cytosol
What is mitosis - ...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 - ...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 - ...are the molecules of life and are built around chains of carbon
atoms that are often quite long.
Some functions of lysosomes - ...they breakdown, degrade and digest safely within a cell
What type of epithelium would you find dense microvilli( lining intestines and kidney tubules) - ...
simple cubodoidal epithelium
Where would you find Pseudostratified columnar epithelia - ...ciliated is found in the trachea and
upper respitory tract; non ciliated is found in the male sperm
Major functions of fat - ...provides reserve fuel for cell, insulates against heat loss, supports and
protects organs
, What is metabolism - ... 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) - ...they provide strentgh with there
crosslinks which resits being pulled apart, as well as cushoining.
What produces the most ATPs during cellular respiration - ...glucose, and the electron transport
chain
What is a frontal section/cut - ...through torso- divides the body by anterior(front) and
posterior(back)
Improperly digesting nutrients, may indicate a problem of which tissue layer - ...simple epithelium
When does the body normally use proteins for energy (ATP) - ...When the body is in starvation
mode( doesnt have enough carbohydrate or fat calories for Atp production.
Normal constituents of the plasma membrane - ...seperates the inracellular fluid wihin the cell
and the extracellular fluid outside the cell.
What are endocrine glands - ductless glands - secrete hormones directly into blood or lymph ex.
pituitary, thyroid
What is phagocytosis - ...cell eat- ingestion of bacteria or other material
The primary function of cellular respiration - ...metabolism to form ATP
The basic structural material of the body is made of what - ...Proteins
