Question

Which of the following organelles are involved in making, transporting, or processing proteins in the cell? I. Mitochondria and chloroplasts II. The nucleus and ribosomes III. Rough ER, Vesicles and the Golgi Apparatus IV. Smooth ER and Lysosomes A. I and II only B. I, II, and III only C. II and III only D. I, II, III, and IV

Answer 1

Ответ:

C

Объяснение:

Proteins are allways connected with ribosomes and never with mitochondrias.

Answer 2

The correct answer is C. II and III only.

The organelles involved in making, transporting, or processing proteins in the cell are:

II. The nucleus and ribosomes: The nucleus contains the DNA that encodes the instructions for protein synthesis. Ribosomes are responsible for protein synthesis.

III. Rough ER, Vesicles, and the Golgi Apparatus: The rough endoplasmic reticulum (ER) is involved in protein synthesis and folding. It has ribosomes attached to its surface, which produce proteins. Vesicles transport proteins from the rough ER to the Golgi apparatus. The Golgi apparatus modifies, sorts, and packages proteins for transport to their final destinations.

Therefore, the correct answer is C. II and III only.
