Photosynthesis, the starting point for energy's travels through life

We have also learnt that photosynthesis is a vital process that occurs in order to create glucose and oxygen, by transforming carbon dioxide and water in the presence of light energy.

The glucose produced in photosynthesis may be used in various ways by plants and algae.

Photosynthesis in plants and a few bacteria is responsible for feeding nearly all life on Earth. It allows energy from the sun to be converted into a storable form, usually glucose, which plants use to grow and thrive. Photosynthesis also generates the oxygen that animals need to survive. But here we animals repay the favor. We exhale the carbon dioxide that plants need for photosynthesis. Here, take a closer look at the oxygen/carbon dioxide cycle and the process of photosynthesis.

This tutorial introduces photosynthesis

Some glucose is used for respiration to release energy. Some is used to produce:

Because it is not always sunny, the rate of photosynthesis can vary. Trees also store some of the glucose for future use in the form of insoluble starch in the tissue of the trunk, branches and roots.

During the process of photosynthesis, carbon dioxide plus water in the presence of sunlight, enzymes and chlorophyll produce glucose and oxygen as waste product.

Chemical formula for photosynthesis

In the results the pattern is that when the light intensity is higher the readings are generally higher.

The size of nanoparticles used in cancer treatmentshould be large enough to prevent their rapid leakage from tumortissue into blood capillaries. On the other hand, the size shouldalso be small enough to avoid capture by macrophages in thereticuloendothelial system (RES). The optimized size ofnanoparticles used in cancer treatment is suggested to be ∼50–100nm to accumulate on tumor tissues utilizing so-called ‘enhancedpermeability and retention’ (EPR) effect (). Sperling systematicallyand analytically reviewed the biological applications of GNPsrecently. However, the majority of biological research has involvedsmall-sized GNPs (5–20 nm) (),which are easily prepared, but are too small to take advantage ofthe EPR effect to target tumors. The mechanism ofcellular uptake of GNPs of large sizes (∼14–100 nm) has previouslybeen reported (,). However, the intracellular uptakedynamics and the biological effects of these large-sized GNPs, inparticular functionalized GNPs such as glucose-capped GNPs(Glu-GNPs), have never been studied in depth. Furthermore, the doseof GNPs used in published studies is high (∼100–10,000 billionparticles per ml) (–), which may induce severe side-effectsand limit its clinical applications. Our aim in this study was tosystematically investigate the minimum effective dose of GNPs,which is critical for clinical trials.

The formula is as follows- Carbon dioxide + water Carbon dioxide and water are chemically combined to produce glucose (the energy source) and oxygen (a waste product)....

The glucose made during photosynthesis is used by the tree for energy to live (respiration) and also for growth and repair. It is transported via the phloem cells to growing shoots where the sugar molecules provide the basic building blocks to make cellulose and lignin; the main ingredients of wood.

BBC - GCSE Bitesize: Storage and use of glucose

The word equation for photosynthesis is: Light [IMAGE]Carbon Dioxide + Water Glucose + Oxygen Chlorophyll Although most of the glucose produced is converted into insoluble starch for storage in the stem, leaves or roots, some is used immediately by the plant to provide via respiration....

The leaves are also responsible for absorbing the sun light needed for photosynthesis to take place. The cells of each leaf contain small organelles called chloroplasts which contain a green substance calledchlorophyll. It is the chlorophyll in the leaf that absorbs the light energy needed to turn the raw ingredients of water and carbon dioxide into glucose and oxygen.

Chemistry for Biologists: Photosynthesis

Photosynthesis takes the raw ingredients of water and carbon dioxide and uses light energy from the sun to make glucose and oxygen. In trees, this process happens on a large scale.
