Photosynthesis allows organisms to access enormous amounts of free energy from the sun and transform it to the chemical energy of sugars. Although all organisms carry out some form of cellular respiration, only certain organisms, called photoautotrophs, can perform photosynthesis.
1 Μαρ 2022 · There’s a lot of information in the Advanced Placement (AP) Biology photosynthesis unit that can distract you from remembering its most important concept: the transformation of light energy into chemical energy, and then its storage in the bonds of carbohydrates.
Photosynthesis consists of two stages: the light-dependent reactions and the light-independent reactions or Calvin cycle. The light-dependent reactions occur when light is available. The overall equation for photosynthesis shows that is it a redox reaction; carbon dioxide is reduced and water is oxidized to produce oxygen:
18 Δεκ 2016 · This section of the AP Biology curriculum covers photosynthesis and the reactions that make harvesting energy from the sun possible. We’ll start by going 2.3 billion years into the past to analyze the origins of photosynthesis. Then, we’ll go over a quick overview of the entire process.
1 Μαρ 2022 · The process of photosynthesis is an essential AP® Biology concept to understand. Photosynthesis is the means by which most of the plant life on Earth gets its energy. All animals receive nutrients either from plants or from animals that get their energy from plants.

photosynthesis occurs in the chloroplasts within cells. The process of photosynthesis occurs in a series of enzyme-mediated steps that capture light energy to build energy-rich carbohydrates.
