The cell membrane, also known as the plasma membrane, is a double layer of lipids and proteins that surrounds a cell and separates the cytoplasm (the contents of the cell) from its surrounding environment. It is selectively permeable, which means that it only lets certain molecules enter and ...
Explain how the directional movement of phosphates from ATP to water can be used to turn on and off proteins, power active transport, and power the directional movement of walking proteins. In what way is the powering of walking proteins distinctly differ ...
Describe the role and function of carbohydrates, lipids, proteins, and fiber to maintaining a healthy and balanced diet. Describe how lipids are digested and absorbed. In the discussion, include all organs and intermediates involved in the process. ...
In a eukaryotic cell, many proteins are made in the rough ER,modified in the Golgi apparatus, and then secreted from the cell. How do the proteins move between the ER and Golgi? How do the proteins move from the Golgi to the plasma me...

Enzyme activities of peroxisomal /3-oxidation sys- tem in the autopsied liver were markedly decreased, and immunoblot analysis revealed that proteins of these enzymes were also deficient. But mRNA activities of these enzymes were present. These results indicate that the enzymes of peroxisomal/3-...
Explain the functions of the main proteins involved in RNA, namely: a. Dicer b. RISC complex c. Argonautes d. RNA-directed polymerases e. RITS complex What is the overall structure of a DNA molecule? What do you understand by the term 'nucleotides'?
Describe the composition of plasma and the function of the different components. Draw or describe an ionic bond (no need to define what element) between 2 atoms. Describe the two components of blood. Describe 3 different uses of the Germanium element in the world. ...
Describe the function of proteins in eukaryotic cells. How are prokaryotic and eukaryotic cells alike? How do they differ? Compare prokaryotic and eukaryotic cells. Describe the cell structure and function of eukaryotes, prokaryotes, and viruses. Define eukaryotic. What is the difference between eukary...
