What is the chemical equation of photosynthesis?
The chemical equation of photosynthesis is the following:6 CO2 + 6 H2O + light --> C6H12O6 + 6 O2
The chemical equation of photosynthesis is the following:
6 CO2 + 6 H2O + light –> C6H12O6 + 6 O2
See lessWhy is the nickname “dark reactions” not entirely correct for the chemical stage of photosynthesis?
“Dark reactions” is not a correct name for the chemical stage of photosynthesis since the reactions of the chemical the stage also occur in the presence of light.

See lessWhat is an example of a lab experiment that shows the variation of the photosynthesis efficiency in relation to different photic energy frequencies to which the reaction is exposed? Was it expected that green light frequency favored the reaction?
The experiment: Plants of same species and ages are placed each under (respecting their photoperiods) light sources emitting only one of the colours of the light spectrum (violet, anil, blue, green, yellow and red). The experiment is executed with each of the colours and after days each plant's deveRead more
The experiment: Plants of same species and ages are placed each under (respecting their photoperiods) light sources emitting only one of the colours of the light spectrum (violet, anil, blue, green, yellow and red). The experiment is executed with each of the colours and after days each plant’s development is compared. Those plants whose development was normal performed satisfactory photosynthesis while those with abnormal development underused the offered light.
Chlorophyll is green because it reflects the green light frequency, i.e., it does not “use” the green range of the electromagnetic spectrum. Thus green light does not favour photosynthesis (curiously green is the light that plants “dislike”).
See lessHow can the hypothesis that asserts that chloroplasts as well as mitochondria were primitive prokaryotes that associated in mutualism with primitive anaerobic eukaryotic cells be corroborated?
The described hypothesis is known as the endosymbiotic hypothesis about the evolutionary origin of mitochondria and chloroplasts. Mutualism is explained as mitochondria and chloroplasts can offer energy and nutrients to the cell in exchange for protection. The hypothesis is strengthened since thoseRead more
The described hypothesis is known as the endosymbiotic hypothesis about the evolutionary origin of mitochondria and chloroplasts.
Mutualism is explained as mitochondria and chloroplasts can offer energy and nutrients to the cell in exchange for protection. The hypothesis is strengthened since those organelles have their own DNA, RNA and protein synthesis machinery and they divide themselves through binary division like bacteria do.
See lessWhat do ATP and ADP mean? What are the roles of these molecules for the cellular energetic metabolism?
ATP is an abbreviation of adenosine triphosphate, a molecule made of adenosine bound to three inorganic phosphates. ADP is an abbreviation of adenosine diphosphate, two molecules of phosphate bound to adenosine. ATP is a molecule that stores energy for the cell. When ATP hydrolyzes and becomes ADP eRead more
ATP is an abbreviation of adenosine triphosphate, a molecule made of adenosine bound to three inorganic phosphates. ADP is an abbreviation of adenosine diphosphate, two molecules of phosphate bound to adenosine. ATP is a molecule that stores energy for the cell. When ATP hydrolyzes and becomes ADP energy is liberated and then consumed by several metabolic reactions of the organism.
See lessWhich are the living beings that carry out photosynthesis? Which is the cell organelle responsible for the absorption of light for the photosynthesis process in plants and algae?
There are many beings (including all animals) that do not carry out photosynthesis. There are also autotrophic beings that do not perform photosynthesis but they perform chemosynthesis. Plants, algae and cyanobacteria are photosynthetic beings.In plants and algae, light is absorbed by chlorophyll, aRead more
There are many beings (including all animals) that do not carry out photosynthesis. There are also autotrophic beings that do not perform photosynthesis but they perform chemosynthesis. Plants, algae and cyanobacteria are photosynthetic beings.
In plants and algae, light is absorbed by chlorophyll, a molecule present in cytoplasmic organelles called chloroplasts.
See lessIn which chloroplast structure are chlorophyll molecules found?
Chlorophyll molecules are placed in an organized manner in order to enhance the exposure to light on the thylakoid surfaces.

See lessWhat are the roles of NADPH and ATP in the chemical stage of photosynthesis?
NADPH acts as a reductant of carbon dioxide, it delivers highly energetic hydrogens to precursor molecules during the glucose formation process. ATP is an energy source for the reactions of the chemical stage.

Free electrons, hydrogen ions and molecular oxygen is liberated, after the water photolysis.
The electrons will replace those electrons lost by chlorophyll molecules in photophosphorylation. The hydrogen ions will be incorporated into hydrogen acceptor molecules (NADP) and later will be used in the synthesis of glucose during the chemical stage. Molecular oxygen is liberated to the atmosphere.
