Biology

Answer:

The correct answer would be levodopa/carbidopa.

Tolcapone is a drug used as an adjunct to levodopa/carbidopa combination medication.

These drugs are used to treat the symptoms of Parkinson's disease.

Tolcapone is used to inhibit enzyme COMT (catechol-O-methyl transferase).

In the brain, levodopa is converted into dopamine which helps in controlling the movement.

Carbidopa helps in preventing the breakdown of levodopa in the blood which allows more levodopa to enter the brain. In addition, it helps in reducing the side-effects associated with levodopa such as vomiting, nausea et cetera.

When a pigment molecule in a light-harvesting complex absorbs a photon of light, what happens to its excited-state electron?.
MA_775_DIABLO [31]

When a pigment molecule in a light-harvesting complex absorbs a photon of light, While returning to its ground state, the electron transfers some of the energy from its excited state to an electron in a nearby pigment molecule.

  • It takes a photon of light energy some distance before it reaches a pigment molecule like chlorophyll.
  • An electron in the chlorophyll is "activated" by the photon. The energy imparted to the electron then moves from one pigment molecule to another until it reaches the reaction center, a pair of chlorophyll a molecules.
  • An electron in the reaction center is then excited by this energy, causing it to break loose and travel to the primary electron acceptor.
  • Therefore, it is said that the reaction center "donates" one electron to the main electron acceptor.

The most distinctive characteristic of leaf mesophyll cells is that they are filled with
Katyanochek1 [597]
<h2>Mesophyll cells</h2>

Explanation:

The most distinctive characteristic of leaf mesophyll cells is that they are filled with many chloroplasts

Mesophyll cells constitute the main body of a leaf, occurring between upper and lower epidermis

Typically, the leaves of temperate-zone plants have two layers of mesophyll cells, the palisade mesophyll on the upper side and the spongy mesophyll on the lower side

The palisade mesophyll is a layer of densely packed, columnar cells which contain many chloroplasts, this layer is responsible for most of the photosynthesis of leaves

The spongy mesophyll is composed of large, often odd-shaped, photosynthetic cells separated from one another by large, intercellular spaces, these intercellular spaces apparently facilitate the exchange of photosynthetic gases
