What is photosynthesis? Write the chemical equation for this process, and briefly describe the stages of photosynthesis

6CO₂+6H₂O-->C₆H₁₂O₆+6O₂

Photosyntheis is the process used by autothropic plants and cyanobacteria to convert light energy into chemical energy stored in the bonds of glucose.

It occurs in two phases

1.Light dependent reaction where sun energy is absorbed and stored in ATP and NADPH and O₂ is produced.It occurs in the thylakoid membrane of the chloroplast.

2.Light independent reactions(Calvin Cycle) where CO₂ is fixated using the energy in ATP and NADPH produced in the light dependent reaction. This process occurs in the stroma of the chloroplast.

answer: the correct option is d. enzyme

lactase and carbonic anhydrase are the examples of enzymes.

lactase is an enzyme, which is present in the small intestine of mammals. it in the digestion of the disaccharide, lactose ( milk sugar) by converting it into two monosachharide, which are glucose and galactose.

carbonic anhydrase is present in the red blood cells. this enzyme plays significant role in the transport of co₂. it in the conversion of co₂ and h₂o into carbonic acid, which is then dissociated into bicarbonate ions and hydrogen ions.
