This song makes it easy to learn how photosynthesis works

You should already know from your GCSE studies that mitochondria are the sites of ATP production, but for “A” level you must be able to explain where all the chemical reactions of tissue respiration take place. Glycolysis, the breakdown of glucose to form acetyl coenzyme A, takes place in the cytoplasm outside mitochondria. The Kreb’s cycle, breaking down acetyl coenzyme A into carbon dioxide and NADPH, takes place in the matrix of the mitochondrion. Some ATP is generated directly during the Kreb’s cycle, but most of the ATP produced in tissue respiration is generated by the electron transfer chain which takes place across the membranes of the mitochondrion. Stalked particles on the inner surface of cristae contain the enzymes required to make ATP from ADP and phosphate.

This tutorial introduces mitochondria

The plant uses the largest molecules to construct cell walls as the plant grows larger.The following equation sums up the photosynthesis reaction:

Sunlight + 6H2O + 6CO2 → C6H12O6 + 6O2
In words, this equation states that sunlight, combined with six molecules of water (H2O) and six molecules of carbon dioxide (CO2), produces one molecule of sugar (C6H12O6) and six molecules of oxygen gas (O2).Through this process, green plants capture energy from the sun, use some of it to function and grow, and store some of it in their plant structure, where it’s available to other organisms when they eat the plants.

Breakdown of Photosynthesis 2

Photosynthesis is defined as the formation of carbohydrates inliving plants from water and carbon dioxide (CO2). It is the mostimportant chemical pathway (series of chemical reactions) on ourplanet. Almost all of the biomass on Earth was initially createdby photosynthesis.
