<u><em>-Describe the electron transport chain. What part of the cells does hit reaction take place in?
</em></u>
The electron transport chain is A group of compounds that pass electron from one to another via redox reactions coupled with the transfer of proton across a membrane to create a proton gradient that drives ATP synthesis. The electron transport chain occurs in the inner membrane of the mitochondria.
<u><em>-What molecule stores the energy that is generated during cellular respiration?
</em></u>
Cells create energy by breaking down the ATP molecules. Thus, cellular respiration is the utilization of oxygen for the synthesis of ATP. Glucose is broken down to supply energy for cellular respiration.
When an ecosystem has a scarce nutrient, that is when there is a nutrient limitation.
So the answer is C. <span>Nitrogen is typically the limiting nutrient in freshwater environments.
This is because Nitrogen is the "scarce" nutrient </span>
Sulfur<span> is an important structural atom in most </span>proteins<span> as </span>sulfur amino acids. It defines its structure. <span>The </span>sulfur<span>-containing </span>amino acids<span>, </span>can<span> be converted into each other but neither </span>can<span>be synthesized in humans. Hope this answers the question. Have a nice day.</span>
A replication bubble forms as the DNA unwinds.
Option C
<u>Explanation</u>:
Replication bubble is the space where the strands of double helical DNA structure are separated with the help of DNA helicase. The strands of the double helical DNA are still in the helix form on the both end of the unwinded DNA stand which gives this region an appearance of a bubble.
DNA unwinding is the first step in replication or transcription of the DNA molecule. DNA helicase separates the two types of "DNA" that are connected by hydrogen bonds with the help of ATP hydrolysis.
