What role do pigments play in the process of photosynthesis

Biology
1 answer:
Ira Lisetskai [31]3 years ago
5 0

Answer:

Pigments absorb the light (capture as much light energy as possible) used in the process of photosynthesis.

Explanation:

Photosynthetic pigments are chemical compounds that absorb and reflect certain wavelengths of visible light, that is, they absorb light and have a color.

They are vital components for the process of photosynthesis, the most important pigment is chlorophyll. Chlorophyll is a large molecule, which captures the energy of sunlight and converts it into high-energy electrons. This occurs during the light reactions of photosynthesis, while high-energy electrons are subsequently used during dark reactions in the synthesis of glucose.

A new DNA strand elongates only in the 5' to 3' direction because _____.
goldenfox [79]

Answer:

d. DNA polymerase begins adding nucleotides at the 5' end of the template

Explanation:

Polymerase DNA always works in one direction, synthesizing the new 5' to 3' oriented chains and adding nucleotides to the 3' end of a new synthesis chain by forming phosphodiester bonds between the phosphate of a nucleotide and the sugar of the anterior nucleotide.  

Because DNA polymerase only acts in a 5' to 3' direction, replication along a chain, the leading chain, occurs continuously. The synthesis of the opposite chain, the delayed chain, occurs discontinuously because the DNA polymerase must wait for the replication fork to open. Over the delayed chain, short segments of DNA called Okazaki fragments (named after Reiji and Tsuneko Okazaki, the scientists who discovered these fragments) are synthesized as polymerase DNA works out of the replication fork. Ligase DNA catalyzes the covalent bonds between Okazaki fragments in the delayed chain to ensure there are no gaps in the phosphodiester skeleton. Finally, the first ones are removed and these gaps are filled by the DNA polymerase.

Deffense [45]

Answer:

Option C

Explanation:

Dr. Leland Hartwell used baker’s yeast, <em>Saccharomyces cerevisiae</em>, as a model system, which was a highly suitable model for cell cycle studies. He introduced the concept of Checkpoints where he said cells are arrested if damaged so that the cells repair system can work to correct such damages. Dr. Paul Nurse used a different type of yeast, <em>Schizosaccharomyces pombe</em>, a type of yeast distantly related to the baker's yeast as a model organism.
