Along the way, the cytochrome complex pumps protons across the thylakoid membrane (into the lumen) to generate a proton gradient, the energy of which will eventually be harvested for ATP synthesis.

To get this energy, many organisms access stored energy by eating, that is, by ingesting other organisms. But where does the stored energy in food originate? All of this energy can be traced back to photosynthesis.

Many of these carbohydrates are produced by photosynthesis, the biochemical process by which phototrophic organisms convert solar energy (sunlight) into chemical energy. Although photosynthesis is most commonly associated with plants, microbial photosynthesis is also a significant supplier of chemical energy, fueling many diverse ecosystems.

Therefore, directly or indirectly, the process of photosynthesis provides most of the energy required by living things on earth. Photosynthesis also results in the release of oxygen into the atmosphere. In short, to eat and breathe, humans depend almost entirely on the organisms that carry out photosynthesis.

It highlights the necessity of replacing lost water via xylem transport from roots and notes the benefits of transpiration, such as aiding photosynthesis and cooling. Environmental factors like light, temperature, humidity, wind, and soil water availability influence transpiration rates.

It covers the absorption of light, the structure and function of various components, and the generation of energy in the form of ATP and NADPH. These processes involve intricate reactions, including charge separation and electron transfer, to convert solar energy into chemical energy.

It describes the roles of these carbohydrates, their biosynthetic pathways, and the involved enzymes, particularly glycosyltransferases. The regulation of sucrose biosynthesis, mechanisms of glycosyltransferases, and structure-function relationships of enzymes like sucrose synthase and starch synthase are discussed.
