The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles, attached to bones or internal organs and blood vessels, are responsible for movement. Nearly all movement in the body is the result of muscle contraction.

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.

nerve networks that include both sympathetic and parasympathetic fibers that reach the same structure are called nerve networks
Lelechka [254]

Central plexuses are the name for nerve networks with sympathetic and parasympathetic fibers that all travel to the same structur automobile plexuses.

<h3>What is the term for a sympathetic and parasympathetic network?</h3>

Involuntary physiological activities including heart rate, blood pressure, breathing, digestion, and sexual arousal are regulated by the autonomic nervous system, a part of the peripheral nervous system. Sympathetic, parasympathetic, and enteric are its three physically separate divisions.

<h3>Can a nerve have both parasympathetic and sympathetic functions?</h3>

Both sympathetic and parasympathetic nerves innervate several target areas (eg the heart, the iris muscle, some salivary glands, the gastrointestinal tract and pelvic organs).
