Flashcards in 2- Dynamic Cells: Molecules On The Move ✅ Deck (65)
The passage of a substance across a cell membrane against the concentration gradient
The process of cell regulated cell death, mainly done by lack of signalling to a cell.
Related to cancer in that when apoptosis fails and cells rapidly divide
Proteins that transport so lutes across the phospholipid bilayer of the plasma membrane by a change in shape of the protein.
Proteins embedded in the phospholipid bilayer of the plasma membrane that, when open allow the movement of solutes into and out of the cell
The substance containing DNA, proteins, and some RNA, of which chromosomes are made
A structure containing proteins and a single DNA molecule that carries genetic information
The change in concentration of a substance over distance or across a membrane
The network of microtubules and microfilaments found in eukaryotic cells
A quality of membranes to allow only certain kinds of particle through
The process of net passive movement of substances from a region of higher concentration to one of lower concentration
The process where by particles enter an animal cell intact without passing through the structure of the plasma membrane
The system of membrane lined cavities in the cytoplasm of eukaryotic cells that is the site of protein synthesis
An organism that consists of cells containing distinct organelles including a nucleus, and other membrane bound organelles
A process by which substances are removed from the cell
Extra cellular matrix
The material between the cells of multicellular organisms
The process whereby a substance is transported across the plasma membrane of a cell, using transport proteins that are specific to each solute transported but without the expenditure of energy
Fluid mosaic model
A membrane bound organelle of a cell comprising of stacks of four to ten disk shaped cisternae.
A solution that is lower in solute compared to another
A solution that is higher in solute compared to another
A group of protein filaments that make up one component of the cytoskeleton of eukaryotic cells, they form rope like bundles that provide tensile strength for the cell.
A solution with solute concentration equal to another solute
A membrane bound vesicle of an animal cell that contains digestive & decomposing enzymes
A thread like structure made of protein that is involved in various from of cellular movements
Small tubules made up of protein tubulin; they are a major component in the cytoskeleton, that is maintaining cell shape
Describes agents(cells organisms, substances) that are not recognised by the immune system as being part of the organism
The membrane of phospholipids around the nucleus of the cell
A dark staining sub-organelle found within the nucleus of the cells
An organelle bound by a double membrane found within eukaryotic cells
