Lesson 1.1 : Cell Flashcards
It is called the power house of cell.
MITOCHONDRIA
What are the four processes of cellular respiration.
Glycolysis
Pyruvate Oxidation
The citric acid or krebs cycle
And oxidative phosphorylation
It is derived from the greek word: pro-before & karyon- nucleus.
PROKARYOTIC CELLS
It is derived from the greek word: eu- true & karyon - nucleus.
EUKARYOTIC CELLS
Nucleus is the site for informational components collectively called as _____.
CHROMATIN
This cell organelles contains more than 95% of the cells DNA and is the control center of the cell.
NUCLEUS
It is a double membrane structure that separates nucleus from the cytosol.
NUCLEAR ENVELOPE
It is embedded in the nuclear envelope and they control the movement of proteins and ribonucleic acid across the nuclear envelope.
NUCLEAR PORE COMPLEXES
It is a dense mass associated with the nuclear envelope.
NUCLEOLUS
It contains various enzymes: DNA polymerase and RNA polymerase for m- RNA synthesis.
NUCLEOPLASM
How many mitochondria may contain in mammalian liver?
800-2500 mitochondria
What are the two concentric membranes that have different properties and biological function.
Outer Mitochondrial Membrane and Inner Mitochondrial Membrane
It mainly consists of phospholipids and traces amounts of cholesterol,also contain Porin.
Outer Mitochondrial Membrane
Its rich in proteins with a ratio of lipid to protein of 0:27:1 weight.
Inner Mitochondrial Membrane
What do you call a inner member which is highly folded and referred to as _____________.
Cristae
What do you call a space between the outer and inner membrane?
Intermembrane space
What do you call the region enclosed by the inner membrane.
Mitochondrial matrix
It is responsible for protein synthesis transport, modification, storage,and secretiin.
Endoplasmic reticulum
These membranes and the aqueous channel they enclosed are called ________.
Cisternae
What are the 2 types of Endoplasmic reticulum?
Rough Endoplasmic reticulum and Smooth Endoplasmic reticulum
This is a type of Endoplasmic reticulum which also known as “ergastoplasm”.
Rough Endoplasmic reticulum
This is a type of Endoplasmic reticulum which does not have ribosome.
Smooth Endoplasmic reticulum
This also known as “ Dictysomes “.
Golgi Apparatus
These vesicles move to and fuse with the plasma membrane where the contents may be expelled by process called _____________.
Exocytosis
This an organelle which contains packet of enzymes.
Lysosomes
It is used as a marker enzyme for this organelle.
Acid phosphatase
It is a small organelles aka “microbodies”
Peroxisomes
It is composed of complex networks of fine structure.
Cytoskeleton
It is a long, unbranched slender cylindrical structure which is responsible in the assembly and disassembly of the spindle structure during mitosis.
Microtubule
It more slender cylindrical structures composed of contractile protein ( actin ).
Microfilaments
It is a very fragile tubes that forms the transient network in the cytosol.
Microtrabeculae
It is the simplest structure of the cell.
Cytoplasm
