All the following are properties of the endoplasmic reticulum except: some parts have embedded ribosomes. it is usually found immediately surrounding the nucleus. its main role is hydrolysis of macromolecules. it is involved with synthesis of lipids. it appears as a group of membranous sacs and tubes.

00:01 All right, so we're taking a look at the endomebrane system, which is a system that is completely focused, shall we say, on making proteins.

00:15 So let's go one by one into each of these organelles that could potentially have or have not any impact on this endome membrane system and the synthesis and transported proteins.

00:29 So first, let's go with the ribosome.

00:32 Now, the ribosome is probably the most well -known of the protein synthesis organelles.

00:41 It turns mrna and it makes it into protein.

00:52 So we know that in the endome membrane system, which is completely obsessed with making protein, that a ribosome is definitely going to be a part of it.

01:02 Now, what about golgi bodies? so the golgi bodies, or you might have seen them call the golgi apparatus somewhere, the golgi bodies are in charge of modifying and packaging proteins.

01:26 Now, what does that mean? well, proteins need to know where in the cell to go.

01:35 So sometimes the golgi bodies add little tags.

01:39 Onto them to tell them where to go.

01:41 They also package them in little vesicles to ensure that there are a protective barrier around them so that they can get where they need to go.

01:54 So the goldie butters are definitely involved in proteins and synthesis.

01:58 Now, what about the nucleus? now, the nucleus is kind of a more behind -the -scenes member, but the nucleus houses dna, if you'll remember...
