chapter 7 practice test sections 3-4

What are 3 types of fibers found in the cytoskeleton and what are their function?

• microtubules - transport organelles, help create structures like cilia and flagella

• mitochondria- helps power the cell

• microfilaments- aid in cytoplasmic streaming

  and cell division

• lysosomes- help breakdown large molecules and cellular waste

• intermediate filaments- gives the cell structure, organize organelles, and tether the organelles in place

this organelle produced enzymes that break proteins into amino acids that can be reused for protein synthesis. what is it

this organelle play a part in protein synthesis by processing, sorting, and transporting proteins received from the endoplasmic reticulum

this organelle cantains its own ribosomes and DNA in which it uses to its own proteins. in which it uses to regulate its energy production .
