Hello there.
Which of the following explains why mitochondria appear much less elongated in electron micrographs than they do in images produced by fluorescence microscopy?
C. cross-sectioning of mitochondria gives misleading
Cell membranes do not make nutrients (or energy) for the cells. This is the function of the mitochondria by the electron transport chain, tricarboxylic acid cycle, and beta oxidation. The cell membrane is responsible in holding the cytoplasmic components of the cells. The cell membrane is also involved in substance regulation by acting as a semi-permeable membrane for simple diffusion as well as the site where carrier proteins are embedded for facilitated diffusion (not ATP requiring) and active transport (ATP requiring). The cell membrane is also involved in cell to cell recognition because receptors are also embedded in the cell membrane.
If you mean periodic table then it would be atomic number
Answer:
The correct answer would be D.Alveolar sacs are surrounded by thin capillaries where gases can be exchanged.
Alveoli are tiny sacs which form the site of gas exchange in the lungs.
The features of alveoli which help in gas exchange are:
- They increase the surface area in the lungs thus, more space is available for gas exchange.
- They have very thin walls, as thin as the thickness of a single cell only.
- They are surrounded by a bunch of thin capillaries which exchange gases with alveoli.
