What is meant by oxygenic photosynthesis?
Definition. Oxygenic photosynthesis is a non-cyclic photosynthetic electron chain where the initial electron donor is water and, as a consequence, molecular oxygen is liberated as a byproduct. The use of water as an electron donor requires a photosynthetic apparatus with two reaction centers.
What is a simple definition of photosynthesis?
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
How does anaerobic photosynthesis work?
Anaerobic photosynthesis, also known as anoxygenic photosynthesis, is the process by which certain bacteria use light energy to create organic compounds but do not produce oxygen. Anaerobes are those bacteria that cannot use oxygen to generate energy. This process is known as oxygenic or aerobic photosynthesis.
What is energy’s role in photosynthesis?
photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
What is the difference between oxygenic and Anoxygenic photosynthesis?
As a result of photosynthesis, gaseous oxygen is released to the environment. The key difference between oxygenic and anoxygenic photosynthesis is that oxygenic photosynthesis generates molecular oxygen during the synthesis of sugar from carbon dioxide and water while anoxygenic photosynthesis does not generate oxygen.
What is oxygenic photosynthesis Class 10?
Oxygenic photosynthesis is more common in plants, algae and cyanobacteria. During this process, electrons are transferred from water to carbon dioxide by light energy, to produce energy. During this process, plants take in carbon dioxide and expel oxygen into the atmosphere.
What are the 3 types of photosynthesis?
The three main types of photosynthesis are C3, C4, and CAM (crassulacean acid metabolism). In college I had to memorize some of their pathways and mechanisms, but I will highlight what gives one an advantage over another and what types of crops, forages, and weeds have specialized C3 and C4 photosynthesis.
What does anaerobic mean in science?
Definition of anaerobic 1a : living, active, occurring, or existing in the absence of free oxygen anaerobic respiration anaerobic bacteria. b : of, relating to, or being activity in which the body incurs an oxygen debt anaerobic exercise. 2 : relating to or induced by anaerobes.
What is oxygenic and Anoxygenic photosynthesis?
Because oxygen is generated as a byproduct and is released, this type of photosynthesis is referred to as oxygenic photosynthesis. However, when other reduced compounds serve as the electron donor, oxygen is not generated; these types of photosynthesis are called anoxygenic photosynthesis.
What is the formula for the process of photosynthesis?
If we were to write a formula for photosynthesis, it would look like this: 6CO2 + 6H2O + Light energy → C6H12O6 (sugar) + 6O2 The whole process of photosynthesis is a transfer of energy from the Sun to a plant. In each sugar molecule created, there is a little bit of the energy from the Sun, which the plant can either use or store for later.
What foods link back to the process of photosynthesis?
Although there is a large variety, each item links back to photosynthesis. Meats and dairy products link to photosynthesis because the animals were fed plant-based foods. The breads, cereals, and pastas come largely from grains, which are the seeds of photosynthetic plants. What about desserts and drinks?
Where does stage one of photosynthesis take place?
Stage One: Light Reactions. In the light-dependent process, which takes place in the grana, the stacked membrane structure within chloroplasts, the direct energy of light helps the plant to make molecules that carry energy for utilization in the dark phase of photosynthesis.
How is the energy from the Sun used in photosynthesis?
The Sun! The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar (glucose) and oxygen gas. After the sugar is produced, it is then broken down by the mitochondria into energy that can be used for growth and repair.
