Answer: They help control what enters and leaves the cell.
Explanation: carbohydrates also help the immune system identify if the cell is foreign or not.
Answer:
Whereas both bacteria and archaea lack a nuclear envelope and membrane-bound organelles, archaea and eukaryotes have similarities beyond those seen between bacteria and eukaryotic cells. Bacteria have the macromolecule peptidoglycan in their cell walls; archaea and eukarya lack this polymer.
Explanation:
Answer:
Cilia and flagella are projections from the cell. They are made up of microtubules , as shown in this cartoon and are covered by an extension of the plasma membrane. They are motile and designed either to move the cell itself or to move substances over or around the cell.
Explanation:
Answer:
B. ensure the production of GTP in the case of succinyl-CoA
Explanation:
Succinyl CoA like acetyl-CoA has a thioester bond with very negative free energy of hydrolysis. In this reaction, hydrolysis of the thioester bond leads to the formation of phosphoester bond with inorganic phosphate. This phosphate is transferred to histidine residue of the enzyme and this high energy unstable phosphate is finall transferred to GDP resulting in generation of GTP.
Hence the answer is B. ensure the production of GTP in the case of succinyl-CoA.
