This structure synthesizes protein Right Ans - Ribosome
This structure processes and packages proteins for delivery Right Ans -
Golgi apparatus
Repository of genetic information Right Ans - Nucleus
A cell structure that forms a maze of passageways in which proteins and other
materials are carried from one part of the cell to another. Synthesis steroid
hormones and folds proteins Right Ans - Endoplasmic Reticulum
ribosome synthesis Right Ans - Nucleolus
Delivers proteins that are secretes to their destinations Right Ans - visicle
An organelle containing digestive enzymes Right Ans - Lysosomes
Eukaryote has membrane bound organelles and a nucleus; prokaryote has
genetic material free floating in a cell membrane Right Ans - What is the
difference between eukaryote and prokaryote?
The nucleolus is inside the nucleus and is composed of RNA and contains most
of the cellular DNA. Right Ans - What is the difference between the
nucleolus and nucleus?
Microtubules add strength to the cell structure, they support and move
organelles from one part of the cytoplasm to another. They also facilitate

Isotonic Right Ans - A __ solution has the same osmolality as normal body
fluids
muscle cell Right Ans - a myocyte is a
A molecule that binds specifically to another molecule, usually a larger one.
Right Ans - ligand
pouchlike infoldings that sequester bits of extracellular fluid containing a high
concentration of Ca2+ close to the membrane; when calcium channels open
here Ca2+ influx occurs rapidly. May be important locations for receptors or
for entry of molecules into the cell. Right Ans - Caveolae
translating mechanical stimuli into biochemical signals Right Ans -
Mechanotransduction
