,What are ribosomes? - ANS✔✔--RNA-protein complexes (nucleoproteins) that are
synthesized in the nucleolus and secreted into the cytoplasm through pores in the
nuclear envelope called nuclear pore complexes (NPCs)
Where can ribosomes be found? - ANS✔✔--cytoplasm and rough ER
Apoptosis - ANS✔✔--A programmed cell death that is regulated or programmed.
Cellular self-destruction for elimination or unwanted cell populations
Necrosis - ANS✔✔--Rapid loss of the plasma membrane structure, organelle
swelling, mitochondria dysfunction
what are ribosomes chief function? - ANS✔✔--provides sits for cellular protein
synthesis
What is the Golgi apparatus (complex)? - ANS✔✔--a network of flatten, smooth
membranes and vesicles frequently located near the nucleus of the cell
What does the Golgi apparatus do? - ANS✔✔--takes proteins from the ER and
processes/packages them into small membrane-bound vesicles called "secretory

metabolism , and energy production
What does the inner membrane of mitochondria contain? - ANS✔✔--enzymes of the
respiratory chain and are essential to the process of oxidative phosphorylation that
generates most of the cell's ATP

and metabolizes what three things (3)? - ANS✔✔--1- metabolic
2- urea and heme synthesis
3- carbs, proteins, and lipids
