Cell structures
What are organelles?
Parts of a cell that perform specific functions for the cell
What is the Golgi apparatus
It sorts and transports proteins
What is selectively permeable?
Cell membrane quality allowing some things and not others into the cell.
Organic compounds usually come from living things. They contain what 3 elements?
C, H, and O
What are lipids?
These are fatty compounds that come from fats and oils in our diet.
Its function is storage of water and minerals
vacuole
It is the cell control center. It containes DNA
nucleus
Movement of molecules from an area of higher concentration to lower concentration with the help of protein transporter.
facilitated diffusion
What are polymers?
Large organic molecules that consist of repeated linked units called monomers
These are the small units that make up proteins.
amino acids
This type of cell has no nucleus. Bacteria is one example of this type of cell.
prokaryotic
transforms or makes energy in the form of ATP during cellular respiration
Mitocondria
This is the diffusion of water
osmosis
This reaction occurs when a polymer breaks apart and gives off water.
hydrolysis
Sugars the body can quickly use for energy are called
carbohydrates
Maintains homeostasis by controlling what enters and leaves the cell
plasma or cell membrane
this organelle processes proteins
endoplasmic reticlum
Movement of molecules from an area of higher concentration to lower concentration without the help of protein transporter.
simple diffision
This is an organic acid mainly present in the chromosomes in the nucleus, cytoplasm of cells and certain cell organelles like chloroplast and mitochondria. It mainly functions as the genetic material for all living cells.
nucleic acid
These bonds join these together to form proteins from amino acids
peptide bonds
Digests waste material within the cell
lysosome
in the center of the nucleus; synthesizes ribosomes
nucleolus
This aspect of the phospholipids molecule keeps the membrane from dissolving in water
non-polar (hydrophobic) tails
The four major categories of organic compounds.
carbohydrates, proteins, lipids and nucleic acids
These are proteins that act as catalysts - they speed up reactions
enzymes
