It's main function is to produce ATP, the energy currency of the cell. The mitochondria take fuel (glucose) and essentially burns it. The energy given off by oxidizing the fuel is harnessed by causing ions to move across a membrane, kind of like pumping water. The ions then flow down through a protein which synthesizes ATP much like the water then flows down through a dam to generate electricity.
Answer:
D. In eukaryotes there are introns
Good luck!
<span>Exons from the same gene (like you said above) could be spliced in different ways to make different 'mRNAs'.</span>
Answer:
The correct answer is b) mediate cell-to-cell recognition
Explanation:
Cell to cell recognition is necessary for a cell to know and distinguish its neighbor cells. Cell adhesion is one of the examples cell to cell communication when a cells comes in contact with other cells by interaction with their specialized protein complex.
This contact between cells is accomplished by plasma membrane components like carbohydrates that are attached to proteins and lipids which makes glycoproteins, glycolipids, and glycolipoproteins.
This cell to cell communication is important for cell to proliferate and function together in organs like in liver, liver cell only works when they are surrounded by more liver cells.
So the right answer is b) mediate cell-to-cell recognition.
