Modeling the Calvin Cycle Exploration
galina1969 [7]

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.

Can you tell the difference between the original and the replicated strand
kati45 [8]

Answer:

Original strand is the old strand and replicated strand is new strand.

Explanation:

DNA is replicated by the semi-conservative way which means the new strand is replicated over the old strand and one DNA duplex has one new strand and one old strand. So the original strand is the old strand and the replicated strand is the strand that is synthesized over the original strand.

In DNA the replicated strand is made by adding nucleotides complementary to the opposite nucleotide present in the template or original strand. Adenine and thymine make complementary base pairing with each other and guanine and cytosine makes complementary base pairing with each other.

jarptica [38.1K]

Answer:

Water has properties of cohesion and adhesion.

Explanation:

The single Hydrogen atom and double Oxygen atoms attach to each other in such a way their are minute polar polarity differences.  Electron bonds will combine to form one side of the compound as being positive and the other side positive.  Positive side of other H2O molecules will attach to the negative side.  This bond causes water to adhere to sides of a glass test tube.

Will also create a bead when it drips on another non-porous surface.  Adding soap will break the bead (surfactant).  Water is the perfect solvent.
