How many distinct stages must occur between the point when light first encounters chlorophyll and the point at which
Novay_Z [31]

Explanation:

<u>Three.</u>

Photosynthesis produces glucose and O2 from inorganic CO2, light energy and water.  This occurs in distinct steps: 1) light fixation,  2) electron transport and NADPH production 3)  ATP generation, then 4) carbon fixation and carbohydrate production.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

Further Explanation:

Photosynthesis is a chemical process, essential to plant and other primary producers producing energy. As oxygen is emitted, energy in the form of glucose molecules is created from light, water, and carbon dioxide. It happens in several complicated stages, photosynthesis is a speed-limited process, depending on several factors including concentration of carbon dioxide, ambient temperature and light intensity; energy is extracted from photons, i.e. light particles, and water is used as a reduction agent. It occurs in the thykaloids, where pigment molecules live like chlorophyll.

Photosynthesis occurs in several complex steps and is a reaction of a small duration, depending on several fa factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II.

Additionally,

  • Water (H2O) divided into H+ and OH-by light during photolysis serves as a source of oxygen along with acting as a reduction agent; it reduces the NADP molecule to NADPH by supplying H+ ions and generates molecules of the energy storage molecule ATP through an electron transport chain.
  • This happens in the thykaloids, where pigment molecules reside like chlorophyll.
  • Later, NADP and NADPH are used in dark reactions during the Calvin cycle, where monosaccharides or sugars such as glucose are produced after several molecules have been modified. These store energy in their bonds which in the mitochondria can be released in respiration.

True or False? The pharynx and larynx are generally not coordinated during swallowing in an unresponsive person, making them mor
alexandr1967 [171]
<h2>Correct Answer is True</h2>

Explanation:

  • True.
  • During swallowing, the pharynx changes from airway to a food channel channel.During mastication, the food bolus  aggregates in the pharynx before swallow commencement.
  • <em>The structures in the oral pit, pharynx and larynx serve various capacities in breathing, talking, rumination and swallowing, </em>
  • Unsourced material might be tested and removed.
  • The nasal cavity, The pharynx is the piece of the throat behind the mouth and  larynx the cylinders going down to the lungs and stomach .
  • Nourishment and fluid pass in reverse into the throat on their way to the stomach. Air pass out through the larynx and into the trachea.
