Chapter 10, Problem 20CQ

(a)

Summary Introduction

To explain: Whether a protein similar to porin or glucose transporter is responsible for transporting ribosomes into the cell.

Concept introduction: The ribosome is a non-membranous structure found in the cytoplasm of the cell. It is the core organelle for the protein synthesis. It can be found free or attached with rough endoplasmic reticulum. The porin is a trans-membrane protein which allows the molecules or ions to pass across the membrane. The glucose transporters are considered to be the transport of glucose according to the concentration of the molecules,

(b)

Summary Introduction

To draw: Why the free energy is required to move a ribosome from the nucleus to the cytoplasm.

Concept introduction:  Ribosomes are a non-membranous structures found in the cytoplasm of the cell. They are the core organelle for the protein synthesis and found to be free or attached with rough endoplasmic reticulum.
