Steroids
are complex structure four connected rings of carbon atoms. They are cholesterol which is in all body cells and used to synthesize other steroids:sex hormones, such as estrogen, and testosterone and several hormones from the adrenal glands.

Waxes
are comprised of an ester of a long-chain alcohol and a fatty acid. Many plants have leaves and fruits with wax coatings to help prevent water loss.

Phospholipids
consist of Glycerol portion and fatty acid chains. Only two fatty acids chains; in place of the third is portion that include a phosphate group. THe phosphate portion is soluble in water [hydrophobic] forms the ''head'' of the molecule, while the fatty acids portion is insoluble in water [hydrophobic] and forms a ''tail''.

Fats
to store energy for cellular activities. Carbohydrates fat molecules are composed of carbon, hydrogen and oxygen atoms.

The light-independent reactions of photosynthesis, also known as the Calvin cycle, use and produce a variety of molecules. Sort
Margaret [11]

Molecules brought in and used in the calvin cycle - Carbon dioxide (CO_2) , Ribulose bisphosphate (RuBP)

Molecules produced during the calvin cycle that leave the cycle - a few of the glyceraldehyde-3-phosphate (G3P), NADP+

Molecules used and regenerated within the calvin cycle - most of the Glyceraldehyde-3-phosphate (G3P) , NADPH

<u>Explanation:</u>

Calvin cycle is the light independent reaction that takes place in the stroma of the chloroplast. Calvin cycle uses ATP and NADPH produced during the light reaction. Calvin cycle occurs in 3 steps, they are:

1. Carbon fixation - (CO_2) combines with Ribulose bisphosphate (RuBP) to form 2 molecules of 3-phosphoglyceric acid (3-PGA).

2. Reduction - ATP and NADPH is used to convert 3-PGA into glyceraldehyde-3-phosphate (G3P).

3. Regeneration - some G3P molecule form glucose while other regenerates to form RuBP acceptor.

hershey and chase confirmed that dna, not protein, was the genetic material. how do the results of their two experiments support
Gwar [14]

Hi,

Harshey and Chase did a great experimentation which was basically a two step experiment to prove that DNA and not proteins are the actual carriers of genetic information from parents to offspring.

  • In the first part of their experiment, they used bacteriophages (virus that eat bacteria). They used radioactively labeled sulphur(35S) medium to grow bacteriophages and observed that all the bacteriophages had proteins with radioactive sulphur(35S).
  • In the next step they allowed these phages to infect bacteria and to their surprise, they found that the bacteria did not had radioactively labeled sulphur in them because the coat of bacteriophage stays outside the body of bacteria when it attacks it. This proved that DNA not proteins were the hereditary material.
  • To make their results more reliable, they did a second experimentation in which, they marked the DNA of the phage with radioactive phosphorus 32P. After labeling DNA, they repeated the same experiment and this time, they found radioactive phosphorus inside the bacteria.

<em>This meant that the bacteria had DNA of phage entered inside them and this again proved that DNA not proteins are the hereditary material. You can see attached image for better understanding. </em>

Hope it help!
