Krebs cycle produces NADH which is a high energy electron carrier.NADH is important to the electron transport chain because it initiates the reactions of the chain.
During the electron transport chain process, NADH gives up the H to become NAD+. In this reaction, two hydrogen atoms bearing their two electrons are removed from NADH. The two electrons are passed down through a series of proton pumps to eventually react with oxygen which is the final electron acceptor (when the process is aerobic). By the end of the process 34 ATP molecules are produced.
Oak
Explanation:
Based on the fossil arrangement, we can deduce that the oak was the first to evolve of all the listed fossils.
Fossils are the preserved remains of organisms usually found in rock layers.
To predict the age of fossils, we use one of the principle of relative dating.
The most appropriate one proposed by Williams Smith is the principle of fossil and fauna succession.
It states that "fossils and fauna succeed one another in relative pattern as they evolve".
- The first fossil to evolve will be the oldest one and it will be located at the base of the sequence.
- This is why the choice is oak.
