Question

Proteins play a variety of roles within cells, but there are many steps that must be undertaken to make these proteins and deliver them to where they need to go.

a) no organelles are necessary for the synthesis and transportation of proteins.b) organelles must interact with each other to synthesize and transport proteins.c) organelles act independently when synthesizing and transporting proteins.d) only the organelles shown in the picture are important to cells. rganelles must interact with each other chemically and physically when carrying out an organism's life processes.

Answer 1

Answer: b) organelles must interact with each other to synthesize and transport proteins.

Step-by-step explanation: Organelles must interact with each other chemically and physically when carrying out an organism's life processes.

For example, during protein synthesis:

DNA is transcribed in the nucleus into mRNA.

The mRNA travels into the cytoplasm, attaches to ribosomes, and is translated into a protein.

The protein is pushed into the ER (endoplasmic reticulum) where it is stored for later use or packaged into vesicles.

These vesicles can then be transported to the cell membrane and exported or to the Golgi apparatus where a more complex molecule may be formed. These complex molecules can then be repackaged into vesicles and transported to the cell membrane for export.

Answer 2

Answer: b) organelles must interact with each other to synthesize and transport proteins.

Step-by-step explanation:

The DNA is a genetic material which is converted into mRNA by the process of transcription in the nucleus. The protein synthesis takes place in ribosomes where the translation of mRNA to protein takes place. The proteins are transferred to rough endoplasmic reticulum for the packaging into membrane structures called as cisternae. The proteins are transferred to the golgi apparatus where they are modified, sorted and packed in vesicles. The vesicles take away proteins outside the cell. In golgi apparatus the proteins are tagged with the aminoacids so that they can be targeted to the particular cell.
