Modeling the Calvin Cycle Exploration

Explanation:

The process of photosynthesis is energy-storing because the process converts light energy into chemical energy, which is stored in the bonds of glucose.

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

Further Explanation:

Photosynthesis is a chemical pathway, integral to plant and other primary producers producing energy. Energy is produced from light, water and carbon dioxide in the form of glucose molecules while the oxygen is emitted.

Photosynthesis, which occurs in several complex steps, is a rate-limited reaction, depends on several factors including concentration of carbon dioxide, ambient temperature, and light intensity; energy is recovered from photons, i.e. light particles, and water is used as a reducer. For those removed from photosystem II, water supplies the chlorophyll in plant cell with replacement electrons.

Therefore, water (H2O) split into H+ a by light during photolysis into H+ and OH-acts as a source of oxygen along with functioning as a reducing agent; it reduces the molecule NADP to NADPH by providing H+ ionsand produces molecules of the energy storage moleciule ATP through an electron transport chain. This occurs in the thykaloids, where pigment molecules like chlorophyll reside.

Later, in dark reactions, NADP and NADPH are used in the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules. These hold energy in their bonds, which can be released in respiration in the mitochondria.

Glucose production occurs after G3P production- a molecule of G3P, goes to the cytoplasm from the cycle, to form complex molecules and simple sugars like glucose.

Answer:

I think it's c.

Explanation:

The main function of lysosomes is to help with cell metabolism by ingesting and dissolving unwanted parts of the cell, cell debris, or foreign substances that have entered the cell. So, techinally a street sweeper has the same job as a lysosome since they are getting rid of unwanted stuff.

Climate characterized by mild temperatures is ______. Question 4 options: tropical humid dense temperate
Pachacha [2.7K]

The correct answer is - temperate.

The temperate climates can simply be described as climates with milder temperatures. These climates have changes of seasons, four of them, spring, summer, autumn, and winter. The springs and autumns tend to have mild temperatures, the summers are warm, and the winters are cold, but the highest and lowest temperatures do not come close to the extremely high temperatures in the tropical zone, or extremely low temperatures in the high latitude zones. So these climates have temperatures that are in between the extremes of the low and high altitudes, thus they are milder climates.

Describe how ATP is produced in the light reactions.
Lynna [10]

Answer:

Explanation:

Two reactions take place that produce raw materials for the dark stage:  

  1. Light energy splits the water molecules into <em>hydrogen</em> and <em>oxygen</em>
  2. This process is called <u>photolysis  </u>

The hydrogen is taken up by a hydrogen acceptor called Nicotinamide adenine dinucleotide phosphate (NADP) while oxygen is released as a by-product  .

2 H₂O(l) --------->light energy -------> 4 H + O₂ (photolysis

)

Light energy strikes the chlorophyll molecules and sets in motion a series of reactions resulting in the production of a high energy molecule called <em>Adenosine Triphosphate</em> (ATP)

Hope this helps.
