Endomembrane System

Question 1

Endomembrane system

Answer 1

Group of membranes and organelles in eukaryotic cells that work together to modify, package, and transport proteins and lipids.

Question 2

Endoplasmic reticulum (ER)

Answer 2

Series of interconnected membranous sacs and tubules that modifies proteins and synthesizes lipids.

Question 3

Rough ER

Answer 3

Folds and processes proteins and packages them in vesicles;

Vesicles commonly go to the Golgi apparatus (shipping center)

Membranous sac with ribosomes attached

Question 4

Smooth ER

Answer 4

Membranous sacs that make lipids. No ribosomes.

Synthesizes lipids, carbs and steroid hormones

Detox of medications and poison
Stores calcium

Question 5

Golgi apparatus

Answer 5

Sorting, tagging, packing and distributing lipids and proteins

Question 6

Lysosomes

Answer 6

Contain hydrolitic digestive enzymes for digesting all sorts of molecules, including foreign substances, damaged organelles, and molecules to be destroyed.

Question 7

Cytoskeleton

Answer 7

Network of protein fibers that maintain cells shape, secure organelles in positions, allow cytoplasm and vesicles to move within cell, enable cells within multicellular organisms to move

Question 8

3 types of cytoskeleton fibers

Answer 8

Microfilaments
Intermediate filaments
Microtubules

Question 9

Chloroplasts

Answer 9

Harvests light energy for plants
