Which three statements correctly describe the endoplasmic reticulum?
Sunny_sXe [5.5K]

I have searched everywhere, but I have not found the proposals of the question, but I will explain to you what is the endoplasmic reticulum so that you can answer it.

The endoplasmic reticulum is a eukaryotic organelle located in the cytoplasm.

The endoplasmic reticulum is a network of membrane tubules (often interconnected) scattered throughout the cytoplasm of eukaryotic cells. Its membrane, which alone represents more than half of the cellular membrane system, is in contact with the nuclear envelope.

The endoplasmic reticulum can be:

Granular (or rough) (RER) that is to say associated with ribosomes.

Smooth (SER).

The granular endoplasmic reticulum is the place of synthesis (in the associated ribosomes) of the proteins secreted outside the cell and of the proteins and lipids constituting the membranes of the cellular organelles. Golgi, lysosomes, mitochondria, nucleus, ribosomes, vesicles ...). It participates in the correct folding of the proteins that have just been synthesized.

The smooth endoplasmic reticulum participates in cellular metabolism, synthesizing lipids and storing calcium.

Which type of organic molecule is wax?
Elena L [17]
<span>Wax is a simple form of lipid molecule. It consists of a long-chain of alcohol and a fatty acid. Many of the natural occurring wax found in nature are used as ingredients for products found in stores like ointments, hand cream, and cosmetics.

Plants have naturally occurring wax on their leaves and stems; these serve as coatings to prevent them from losing excess water. Other forms of wax found in nature are beeswax, used by bees to make their cones for honey and eggs; sperm whales have spermaceti wax found in their blubber; and carnuba wax, is an ingredient commonly used for car waxes, commonly found in Brazilian palm trees. </span>
