What is the final acceptor of electrons in the electron transport chain?
aksik [14]

The final acceptor of electrons in the electron transport chain is "C" , that is oxygen.

The electron transport  chain is composed of a series of electron carriers that operate together to transfer electrons from donors, like NADH and FADH2, to acceptors such as O2.

The electrons flow from carriers with more negative reduction potentials to those with more positive potentials and eventually combine with O2 and H+ to form water. 

The difference in reduction potentials between oxygen and NADH is large, about 1.14 volts and makes possible the release of a great deal of energy.

maria [59]

Answer:

<em>The pair which is mismatched is fluorescence microscope - uses a fluorescent light.</em>

Explanation:

The fluorescent microscope can be described as a microscope which uses fluorescence and phosphorescence to study organic or inorganic substances. Hence, the fluorescence microscope uses fluorescence  instead of fluorescent light . Fluorescence is the emission of light or other electromagnetic radiation when a material is stimulated by the absorption of radiation while fluorescent is a fluorescent light which we see commonly in rooms.

Which of the following conclusions can be drawn from this graph?
azamat

Answer:

A

Explanation:

We can't see the graph, but I think I found the worksheet online, and so the graph is attached.

The answer cannot be B, as we are looking at a graph of pH, not temperatures. Therefore, we cannot draw this conclusion

The answer cannot be C, as pepsin is a digestive enzyme, and it works best at pH of around 2.

The answer cannot be D, because we can see that arginase and salivary amylase work at pH 7 and above, which is not acidic

The answer is A, because the lines for each enzyme are different, each peaking at a different pH. These peaks represent their optimum temperatures, and the hills of the peak represent the range in which they can work

A healthy cell spends most of its lifetime in
Artyom0805 [142]
<span>The cell cycle consists of three stages: Interphase, Mitosis (division of the nucleus) and cytokinesis (division of the cytoplasm. During Interphase, the cell works and perform its daily normjal activity. So, a cell in a salivary galnd makes saliva in interphase and so on. Most of the time, the cell is working and doing its things, contributing to the normal functioning of the organism. Mitosis is a quick process (we don't want the cell to spend ages dividing... we want it working for our welfare) and cytokinesis is shorter than mitosis, is only the division the cytoplams. So, YES. The answer is Interphase, fortunately for us. </span>
