4. Which pathway represents the flow of electrons during photosynthesis? (1 point) A.) H2O > Photosystem I > Photosystem I
Yuki888 [10]

Answer:

4. The correct pathway for the flow of electron during photosynthesis is mentioned in option D. H_{2}O > <em>NADP </em>> <em>Calvin cycle.</em>

  • Electron is first provided to the photo-system II by the phtolysis of water.
  • Then it is passed to photo-system I with the help of plastoquinone (PQ) and cytochrome b_{6}f.
  • Finally, electron from the photo-system II is used to reduce NADP to NADPH.
  • NADPH and ATP are used in light independent phase or Calvin cycle to synthesize carbohydrate from carbon dioxide.

5. The correct answer is B.) photosynthesis.

  • Photosynthesis is the process by which green plants synthesize glucose or carbohydrate from carbon dioxide and water in presence of sunlight and chlorophyll.
  • In light independent phase of photosynthesis, it requires ATP and NADPH  in order to synthesize food.
  • Lastly, oxidation or breaking down of glucose releases energy and photosynthesis is a anabolic process instead of catabolic one.

Which statement is TRUE?
Phantasy [73]

Answer:

A

Explanation:

All living organisms ranging from unicellular prokaryotes to multicellular eukaryotes contain genetic material (DNA). This genetic material is usually found on structures called CHROMOSOMES. Although, the chromosomes are contained in the genome of all living organisms, there are differences.

The genetic material of the bacteria (a typical prokaryote) is a single DNA molecule that makes up its single circular chromosomal material, unlike in eukaryotes that contains double-stranded DNA molecules on linear chromosomes. This single circular chromosome of bacteria is found naked in a region of their cell called NUCLEOID, as they do not possess a membrane-bound nucleus that houses it (a unique characteristics of eukaryotes).

The mitochondrial and Chloroplast DNA mentioned in the other options are all components of eukaryotic cells. Bacteria, as a prokaryote does not contain this organnelles. Hence, they are not single replica.
