In plants, photosynthesis, occurring in chloroplasts, is an anabolic (bond-building) process whereby CO2 and H2O combine with the use of light (photon) energy. This yields O2 and sugar (i.e. glucose). This occurs in 2 phases: light-dependent and dark (Calvin cycle) reactions, which both continually recycle ADP/ATP and NADP/NADPH.
The catabolic (bond-breaking) process in plants is cellular respiration, in which glucose is broken down with O2 by glycolysis (cytoplasm only) and mitochondrial reactions (Krebs cycle and E.T.C.) to yield CO2 and H2O. These reactions recycle ADP/ATP and NAD/NADH. The CO2 and water produced by cellular respiration feed into the photosynthetic processes, and in turn, the O2 and glucose resulting from photosynthesis supply the respiratory reactions.
Answer:
Alternative splicing explains how it works
Explanation:
Two different transcripts can be produced from one single gene according to the nature of exons and introns of every transcript, which means that a group of exons will form the future mRNA molecule. The nature of this phenomenon is based on the function and local that every transcript will act. These mRNA transcripts are the result of how the RNA polymerase and transcription factors interacts with DNA molecule and therefore selects the number and the size of the exons and introns of each mature mRNA transcript.
