The pigment molecule in green plants that initiates the reactions of photosynthesis is chlorophyll. Chlorophyll is a green pigment that absorbs light energy, converts it into chemical energy, and plays a key role in capturing light for photosynthesis.
The pigment that absorbs light when photosynthesis begins is chlorophyll. Specifically, chlorophyll a is the primary pigment involved, capturing light energy from the sun to initiate the process of converting carbon dioxide and water into glucose and oxygen. Chlorophyll absorbs mainly blue and red wavelengths of light, reflecting green, which is why plants appear green. This light energy is then used in the light-dependent reactions of photosynthesis.

The Calvin cycle is a cycle because it begins and ends with the same molecule, ribulose-1,5-bisphosphate (RuBP). This molecule is regenerated at the end of the cycle after it undergoes a series of reactions that produce sugars used by the plant for energy.
For glycolysis to begin, it needs: - Glucose from eating - 2 ATP molecules, they "prime" the glucose molecule by adding phosphate to it. - 4 ADP and 4 Phosphoric acids to be joined together - 2 NAD molecules in their oxidized formed. Nicotinamine adenine dinucleotide. Then the ten step cycle can begin! :)
The process of glycolysis begins with the splitting of glucose, a six-carbon sugar, into two three-carbon molecules known as pyruvate. This occurs through a series of enzymatic reactions that convert glucose into fructose-1,6-bisphosphate, which is then cleaved into glyceraldehyde-3-phosphate (G3P) and dihydroxyacetone phosphate (DHAP). Both G3P and DHAP can be further processed in glycolysis, ultimately leading to the production of ATP and NADH.

Glucose and oxygen begin the process of respiration.
Vitamin D production begins when a precursor molecule is exposed to ultraviolet light in the skin.
Glucose, a six-carbon molecule, is the starting molecule for glycolysis.
Chlorophyll is the pigment responsible for absorbing light energy when photosynthesis begins. It is found in the chloroplasts of plant cells and absorbs primarily blue and red wavelengths of light, while reflecting green wavelengths, giving plants their green color.
When a molecule absorbs a photon of infrared radiation, its internal energy increases, causing the molecule to vibrate more rapidly. This vibration can lead to changes in the molecule's structure or interactions with nearby molecules, which can have various effects such as heating up the molecule or triggering chemical reactions.
