Term
Which cell organelle synthesizes ATP?
Definition
Mitochondrion
Term
What is the carrier of proteins and ATP synthase?
Definition
electron transport system
Term
Which cell organelle contains circular DNA and ribosomes, and in the matrix contains enzymes of TCA cycle and B-oxidation of fatty cells?
Definition
mitochondrion
Term
Which cell organelle is:
-also known as microbodies
-prevalent in kidney and liver cells
-contain catalase
-generate and breakdown hyd per into water and oxygen, and oxidizes(breaks down) ong chain fatty acids. (up to 22 carbons)
Definition
peroxisomes
Term
Which cell organelle is:
-site of protein synthesis
-found in both prokaryotic and eukaryotic cells
-found in mitochodria, cytoplasm and attached to RER.
Definition
ribosomes
Term
What provides the internal framework for the cell and gives it shape? I also provides cellular movement and binding sites for organelles
Definition
cytoskeleton
Term
What is composed of microtubules, intermediate filaments, and microfilaments?
Definition
cytoskeleton
Term
What looks like straws, generated at MTOC and forms cilia and flagella?
Definition
microtubules
Term
What is responsible for positioning organelles, movement of cells, movement of organelles, and changes shape in cell during embryogenesis?
Definition
microtubules
Term
What looks like a string, composed of G-actin and F-actin. It's functions include muscle contraction, amoeboid movement of phagocytic cells, cytoplasmic streaming, and cleavage furrow during cell division?
Definition
microfilaments
Term
List the 5 steps in production of membrane proteins and secreted proteins?
Definition
1. nucleus transcribe mRNA
2. RER translates polypeptide into lumen; adds sugar residues
3. transport vesicles to Golgi
4. golgi completes glycosylation if needed
5. transport/secretory vesicles carry protein to plasma membrane
Term
Where is ATP generated as well as reducing electrons?
Definition
in the mitochondrial matrix
Term
Where does glycolysis breakdown glucose and generates small amounts of ATP?
Definition
in the cytoplasm
Term
Where are large amounts of ATP generated?
Definition
in the inner mitochondrial membrane
Term
List the 4 tissue types?
Definition
1. epithelial
2. connective
3. muscle
4. nervous
Term
Which type of tissue is found on the skin, lining of mouth, nose, anus, lining of respiratory and digestive tract.
Definition
epithelium
Term
Which type of tissue is: avascular, contiguous, polarized, and lie at the basal lamina.
Definition
epithelium
Term
What do these shapes mean:
-squamous
-cubodial
-columnar
Definition
-squamous = flat
-cubodial = square
-columnar = rectangular
Term
What is a single layer of flattened cell called?
Definition
simple squamous epithelium
Term
What is the name given to simple squamous epithelium lining blood vessels, chambers of the heart and lymphatic vessels?
Definition
endothelium
Term
What is the name given to simple squamous epithelium lining body cavities and free surfaces of organs found in those cavities?
Definition
mesothelium
Term
sinle layer of square cells, that have a centrally located nucleus
Definition
simple cubodial epithelium
Term
What type of cells are found in the thyroid, kidney, salivary glands, and ovaries.
Definition
simple cuboidal epithelium
Term
single layer of rectangular shaped cells, with a elongated nucleus
Definition
simple columnar epithelium
Term
what type of cells are located in the digestive system, kidney, femal reproductive tract
Definition
simple columnar epithelium
Term
what type of cells are a single layer of cells of different heights? Where are they located?
Definition
-pseudostratified epithelium
-respiratory, male urogenital tract
Term
multiple layers of flat cells
Definition
stratified squamous epithelium
