What are lysosomes and what do they do?
Give this one a try later!
saclike structures that originate from the Golgi complex and contain
digestive enzymes. These enzymes are responsible for digesting most
cellular substances to their basic form, such as amino acids, fatty acids, and
carbohydrates
,What happens after endocytosis occurs?
Give this one a try later!
lysosomal enzymes process and digest material
How is endocytosis done?
Give this one a try later!
when the substance to be transported is engulfed by a segment of the
plasma membrane, forming a vesicle that moves into the cell.
What mechanisms cause atrophy?
Give this one a try later!
include decreased protein synthesis, increased protein catabolism, or both
Compare monosomies and trisomes
Give this one a try later!
, monosomies cause more severe physical defects than do trisomies,
illustrating the principle that the loss of chromosome material has more
severe consequences than the duplication of chromosome material.
What are polygenic traits?
Give this one a try later!
traits that are controlled by two or more genes
What makes up the extracellular matrix and what does it do?
Give this one a try later!
(1) fibrous structural proteins (collagen and elastin), (2) adhesive
glycoproteins, and (3) proteoglycans and hyaluronic acid. The matrix helps
regulate cell growth, movement, and differentiation.
What are molecular biologic phenotypes?
Give this one a try later!
can be detected only with a laboratory test
What is the Golgi complex and what does it do?
, Give this one a try later!
a network of smooth membranes and vesicles located near the nucleus.
The Golgi complex is responsible for processing and packaging proteins
into secretory vesicles
What are the four types of necrosis?
Give this one a try later!
coagulative, liquefactive, caseous, and fatty
What is a neutral effect on gene activity?
Give this one a try later!
no effect
What us an alleles?
Give this one a try later!
slight differences seen in a genes DNA sequence across a population
What is signal transduction?
