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. $H_{2}O$ > NADP > Calvin cycle.

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.

For cvd prevention, trans fat in the diet should account for less than ____ percent of calories. 5

Serhud [2]

trans fats can be reduced to less than 1 percent of calories

Reduction in the consumption of trans fats can reduce blood cholesterol and these will consequently lower the risk of coronary heart diseases. Thus, food made from animals such as milk and meat products contain small quantities of Trans fats. However, trans fats can be reduced to less than 1 percent of calories to avoid build of plagues in the arteries called atherosclerosis.

It is actually the 16S rRNA component of a 30S ribosomal subunit that is responsible for recognition of a Shine-Dalgarno sequenc

Diano4ka-milaya [45]

<h2>The correct answer is (D)</h2>

Explanation:

The Australian scientists John Shine and Lynn Dalgarno proposed the Shine Dalgarno Sequence.

The Shine Dalgarno Sequence is found around 8 Bases in upstream of AUG which is a start codon.

In archaea mRNA and bacteria Shine Dalgarno Sequence is a ribosomal binding site.

The Shine Dalagarno Sequence is found in archaea and bacteria.

It is also seen in Mitochondrial transcripts and Chloroplast.
