Card Set Information
What is the basic functional unit of the human body?
What is the formation of the cell membrane?
What are the functions of the intergraded proteins on the membrane?
To allow for transportation through the membrane
What is the nuclear envelop?
It surrounds the nuclues. It contains pores which control the movement of substances in and out of the nucleus.
List the most inner structure to the outer most.
What are nonhistone proteins?
They include enzymes involved in nuclear function such as replication, transcription, DNA repair and regulation of chromatin function.
What forms the Chromtin Complex?
What is a diploid?
A complete set or pair of chromosomes (46)
What is a haploid?
One set of chromosomes (26)
What is a polyloid?
Contains more than two sets of homologous chromosomes.
What is an Aneuploid?
One or two extra chromosomes.
What are the 3 types of cytoskeleton?
1) Microfilaments (actin)
3) Intermediate filaments
What is the functon of Mircofilaments?
Aid in movement
- Local movement - mircovilli in the GI tract
- Sliding filament theory
What is the function of Microtubules?
intracellular movement during meiosis and mitosis
Ciliary and flagellar movement
What is the function of Intermediate Filaments?
What is the function of Mitochondria?
: a smooth outer one and an inner one which is called cristae
A matrix is enclosed by the inner membrane and contains its own DNA
What organelle plays a role in protein synthesis?
Rough Endoplasmic Reticulum
What organelle plays a role in Lipid biosynthesis?
What organelle has cisterna and modifies proteins and exports them to other areas of the cell?
Membrane proteins are collected, sorted, and packaged in the Golgi Apparatus
What is the role of peroxisomes?
Synthesis and degradation of hydrogen
B-oxidation of very long chain fatty acids
Bile acid synthesis
What are tight junctions?
They site close to the surface or cells and dont allow things to penetrate the skin.
What are adherent junctions?
They serve as a bridge connection between cells.
What is the function of a gap function?
allows direct connection between two cells.
