Which organelle makes the proteins that are needed by the cell?

A. cell membrane

B. golgi apparatus

C. ribosomes

D. nucleus

Answer: C. ribosomes

The ribosomes can be found in the endoplasmic reticulum. There are two types of endoplasmic reticulum; they are the smooth endoplasmic reticulum and the rough endoplasmic reticulum. The ribosomes are found on the latter. The ribosomes are organelles responsible for the production of proteins. Proteins are made from all amino acids and the ribosomes are the cellular component responsible for this.

In other words, a cell in need of protein can only synthesize proteins by looking for ribosomes. Ribosomes are found in both prokaryotes and eukaryotes and are part of the endomembrane system. When these proteins are synthesized, the Golgi apparatus helps in transporting and modifying the proteins particularly in a eukaryotic cell. These proteins are then transported further via transport vesicles and then taken to the cell surface.

Math Calculus — AID—

Total time spent: 4 hours 15 minutes (it is equivalent to 255 minutes). Let the flight time from Paris to Glasgow be X. Then the flight time from Glasgow to Paris will be (X+10). We have an equation with one unknown variable: X + 45 + (X+10) = 255 ⇒ X = 100 So the […]

What were the typical crafts for Maya?

How does 3D printing work?

There are three different ways 3D printers work but they all rely on the printer converting a design into individual 2D slices which are then combined to make the final 3D object. The first method uses a pool of chemicals that turns solid when light, typically a UV laser, is shone on to it. The […]

Cigarette smoking causes emphysema.

Nearly everyone knows that smoking causes lung cancer, but did you know that smoking causes a number of other serious lung diseases? These include chronic bronchitis and emphysema, collectively known as chronic obstructive pulmonary disease (COPD). COPD is the fourth largest killer of Australians and smoking is the most important risk factor for COPD. When […]
