Mar 20, 2024 · While there are many steps behind the process of photosynthesis, it can be broken down into two major stages: light-dependent reactions and light-independent reactions. The light-dependent reaction takes place within the thylakoid membrane and requires a steady stream of sunlight, hence the name light-dependent reaction.

During photosynthesis, photoautotrophs use energy from the sun, along with carbon dioxide and water, to form glucose and oxygen.
The overall equation for photosynthesis is:
There are two main stages of photosynthesis: the light-dependent reactions and the Calvin cycle.
•Photosynthesis and cellular respiration are almost opposite processes. Looking at their equations, they differ only in the form of energy that is being absorbed or released. However, they are not simply the reversal of each other, as each one takes place in its own particular series of steps.
•Plants are green because chlorophyll reflects green light. Many people think that chlorophyll is green because it wants to absorb and use green light. However, this is not true. The color we see is actually the color of light that is being reflected. Therefore, chlorophyll reflects green light, while absorbing red and blue light.
Jul 17, 2016 · Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct. The glucose molecules provide organisms with two crucial resources: energy and ...
- Excellent question. The major reasons that I know of: 1) The high energy bonds in ATP are (by definition) unstable, so for long term storage of ene...
- When you add water, you can separate a compound into two. For example in hydrolysis of an ester, when you add water you get alcohol and carboxylic...
- The reason for this is simply because Photosystem I was discovered first, and Photosystem II was discovered second. You're right, it is confusing b...
- Both reactions, the light-depended reaction and the Calvin's cycle OCCURS ONLY in the light (and out of color spectrum, mainly blue and red colors...
- Glucose is utilised in respiration and excess glucose is stored in the form of starch.... The o2 released might be utilised by humans etc
- Pi stands for inorganic Phosphate... It is described in chemistry as the phosphoryl group, i.e. PO3 with a 2- charge.... This phosphate bonds with...
- It is likely that your colored water is not purely filtering those individual wavelengths. As such, the green water is still allowing some blue and...
- Photosynthesis is extremely important! It is the process in plants that allows it to harness energy from sunlight and convert it into chemical ener...
- ATP is Adenosine TriPhosphate, with three phosphates, and lots of energy stored in bonds. ADP is Adenosine DiPhosphate, with two phosphates, and so...
May 6, 2024 · In chemical terms, photosynthesis is a light-energized oxidation–reduction process. (Oxidation refers to the removal of electrons from a molecule; reduction refers to the gain of electrons by a molecule.) In plant photosynthesis, the energy of light is used to drive the oxidation of water (H 2 O), producing oxygen gas (O 2 ), hydrogen ions (H ...
The Two Parts of Photosynthesis. Photosynthesis takes place in two stages: the light-dependent reactions and the Calvin cycle. In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water. The light-dependent reactions ...
Photosynthesis ( / ˌfoʊtəˈsɪnθəsɪs / FOH-tə-SINTH-ə-sis) [1] is a system of biological processes by which photosynthetic organisms, such as most plants, algae, and cyanobacteria, convert light energy, typically from sunlight, into the chemical energy necessary to fuel their activities.
Sep 21, 2021 · These sugar molecules contain the energy that living things need to survive. Figure 5.1.4 5.1. 4: Photosynthesis uses solar energy, carbon dioxide, and water to release oxygen and to produce energy-storing sugar molecules. The complex reactions of photosynthesis can be summarized by the chemical equation shown in Figure 5.1.5 5.1.
