Structure and Composition of Cell Membrane

Despite differences in structure and function, all living cells in multicellular organisms are surrounded by a cell membrane. Just like the outer layer of the skin separates the body from its environment similarly, the cell membrane, also known as 'plasm…

Cell Membrane

The cell membrane is known by different names like plasma membrane or cytoplasmic membrane, or biological membrane. The term "cell membrane" was first introduced by C. Nageli and C. Cramer in the year 1855. Later on, in 1931, the term "plasmalemma" for c…

Prokaryotes vs Eukaryotes

The cell is defined as the basic structural and functional unit of life. The cell membrane bounds it. It is capable of independent existence.

Describe how fully formed ribosomes that are made in the nucleolus move out of the nucleus into the rough endoplasmic reticulum or cytoplasm. Include how they pass through, any localization signals on the ribosomal proteins and the nuclear transport factor that is involved.

Ribosomes in the cytoplasm (cytosol) capture mRNA that can be translated into an enzyme (in this case a protease) to the lysosome. a) Describe what happens from the time the enzyme (protease) begins to form in the cytoplasm until it end up in the lysosome and explain how the enzyme is transported to the lysosome, Explain in terms of the clathrin and thethering proteins

Ribosomes in the cytoplasm capture mRNA that can be translated into an enzyme for the lysosome. a) Explain what happens from the time the enzyme begins to form in the cytoplasm until it ends up in the lysosome and also explains how the enzyme is transported to the lysosome?
