What is the highly organized unit containing organelles called?
cell
unicellular cells - these are the cells that can live on its own like amoeba
multicellular cells - these are the cells that works with other cells.
What is the smallest structure capable of performing all the activities vital to life?
cell
Cells can be visible examples of this are?
yolk of an egg and nervous cell
What are the major parts of the cell?
cell membrane, cytoplasm, and nucleus
What part of the cell separates the interior of the cell to the external/outside?
cell membrane
Cell membrane is a semi-permeable membrane.
Cell membrane is a selectively permeable barrier that controls the movement of substances into and out of the cell.
phospholipids - contains phosphorus and form a double layer of molecules.
What is the layer of the phospholipid that is water loving?
hydrophilic
What is the layer of the phospholipid that is water fearing?
hydrophobic
cholesterol - a waxy fat carried through the bloodstream by lipoproteins and gives added strength and stability by limiting the movement of phospholipids.
What is the definition of the LDL and HDL?
low density lipoprotein and high density lipoprotein
The liver makes up to how many percent cholesterol?
75%
protein - floats among the phospholipid molecules and extend from the inner to outer surface of the cell membrane.
What is the lipid with a carbohydrate and acts as surface receptor and stabilizes the membrane? This is common in brain cells and nerves.
glycolipids
What type of protein is it when it completely penetrate or extend into the lipid bilayer?
integral proteins
What type of protein is loosely attached to the exterior surface of the membrane?
peripheral proteins
Peripheral proteins can sit in top of an integral proteins.
What protein acts up as enzymes to speed up reactions or attach to the cytoskeleton structures to help with the cell shape?
peripheral protein
What protein allows only one type of ion to pass through?
ion channels
What protein does transport specific substances where they are going to bind and transport solute across the membrane by change shape?
carrier proteins
Carrier proteins are also known as what?
transporters
What protein attach themselves to a specific chemical signal and are sensitive to specific extracellular materials that bind to them and trigger a change in a cell's activity?
receptors
What protein distinguishes your cells from anyone else's?
cell identity marker
cell identity marker aka as what?
glycoprotein
What part of the cell is a jelly-like substance within the cell membrane?
cytoplasm
This is the thick solution composed of water, salt, inorganic salts, and other substances of molecules.
cytoplasm
This is the fluid portion of the cell.
cytosol
Cytosol constitutes about how many percent of total cell volume?
55%
What part of the cell consists of protein structure that supports the cell and hold organelles in place?
cytoskeleton
What component of cytoskeleton is responsible for cell organelles movement?
microtubules
What component of cytoskeleton is the key in change cell shape?
microfilaments
intermediate filaments - makes them a great anchor for the organelles that don't move around like the nuclear.
What is the largest component of cytoskeleton?
microtubules
Microtubules are composed of what?
alpha tubulin and beta tubulin
What is the center of microtubule formation?
centrosome
What is the small, cylindrical organelle composed of triplets which contains of 3 parallel microtubules joined together?
