I believe it is a compound, seeing as compounds are basically different types of elements, only combined into one single compound. Please tell me if i'm wrong?

Which component is missing from the process of cellular respiration? Glucose ________ → Carbon Dioxide Water Energy Sunlight Sug
Marrrta [24]

Cellular Respiration is the process of breakdown of sugar molecules, especially glucose to yield energy in the form of ATP. Every organism undergoes cellular respiration.

<h3>What are the requirements of cellular respiration?</h3>

  • Cellular respiration can take place in the presence of oxygen (aerobic) and in the absence of oxygen (anaerobic) to yield energy.

  • In aerobic cellular respiration, the glucose is broken down in the presence of oxygen to yield energy, carbon dioxide, and water. The process is seen in many plants and animals.

Thus, cellular respiration is the process of the breakdown of glucose in the presence or absence of oxygen to yield energy.

How do you do problem bii??
Advocard [28]

Answer:

Explanation:

Trick question. The cathode is where the reduction reaction takes place. The reduction reaction is the gain of electrons.

Pb+2 + 2e^- ===> Pb        The eo for that is - 0.126.

The minus sign indicates that the Pb^2+ is not overjoyed at taking on those two electrons. If it had a say in the matter, it would rather be giving up electrons. In other words, it would rather be the oxidizing equation which would look like this

Pb ===> Pb+2 + 2e^- and the oxidizing potential would be eo = + 0.126

That's what moving right and moving left means. If the eo is - then the preferred reaction is the opposite one.

This is a real language problem and if Znk answers you can take his answer to the bank.
