Answer: After the experiment in step 5
Explanation:
In a scientific investigation, first step is to formulate a question. Second step is to do background research. In third step after background research, a hypothesis is constructed. In order to test hypothesis, an experiment is designed and performed. In the fifth step, data is collected from the experiment and in the last step, conclusions are drawn from the collected data.
Answer:
The Answer is, B, C, And E. I just took it on USATESTPREP.
B) G3P can be used to form the backbone of triglycerides. Glycerol combines with fatty acid tails to form lipids.
C) Two G3P molecules can be combined through anabolic processes to form glucose, a six-carbon sugar required by cells.
E) G3P can be used in to synthesize amino acids, which contain a central carbon, a carboxylic acid group, and a variable R group. These amino acids can then combine to form proteins.

Answer:
B) FADH2 -- FMN of Complex I -- Fe-S of Complex II -- Q -- Fe-S of Complex III -- Cyt c -- Cyt a of Complex IV -- O2
Explanation:
FADH2 and NADH give their high energy electrons to the terminal electron acceptor molecular oxygen via an electron transport chain. As the electrons move through electron carriers of the electron transport chain, they lose their free energy. Part of the free energy of the electrons is used to pump the protons from the matrix into the intermembrane space. Therefore, part of the energy of electrons is temporarily stored in the form of a proton concentration gradient.
NADH gives its electrons to FMN of complex I while FADH2 gives its electrons to the Fe-S center of complex II. Both the complexes are oxidized by coenzyme (Q) which in turn reduces Fe-S centers of complex III. Cyt c of complex IV obtains electrons from complex III and passes them to CuA center, to heme "a" to heme "a3-CuB center" and finally to the molecular oxygen.
So, the compounds arranged with respect to the energy content of electrons in descending order are as follows: FADH2 -- FMN of Complex I -- Fe-S of Complex II -- Q -- Fe-S of Complex III -- Cyt c -- Cyt a of Complex IV -- O2.
