Photosynthesis is an anabolic process during which plants use energy from sunlight to convert carbon dioxide gas and water into sugar molecules.
What type of metabolism is photosynthesis?
Photosynthesis, which builds sugars out of smaller molecules, is a “building up,” or anabolic, pathway. In contrast, cellular respiration breaks sugar down into smaller molecules and is a “breaking down,” or catabolic, pathway.
What type of reaction is photosynthesis?
Photosynthesis is an endothermic reaction. This means it cannot occur without energy (from the Sun). The light required is absorbed by a green pigment called chlorophyll in the leaves.
Is photosynthesis a metabolic reaction?
Photosynthesis is a two-part metabolic process. The two parts of the biochemical pathway of photosynthesis are the energy-fixing reaction and the carbon-fixing reaction.
What kind of reaction is photosynthesis explain why?
Photosynthesis requires energy, making it an endothermic reaction. Light, generally sunlight, is the source of this energy. The process converts the sun’s electromagnetic energy into chemical energy, which is then stored in chemical bonds in the plant. Sunlight is the primary source of energy on the surface of Earth.
What are the 4 factors that affect photosynthesis?
The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature.
What is photosynthesis explain with diagram?
According to the diagram of photosynthesis, the process begins with three most important non-living elements: water, soil, and carbon dioxide. Plants begin making their ‘food’, which basically includes large quantities of sugars and carbohydrate, when sunlight falls on their leaves.
What are the 2 kinds of reaction in photosynthesis?
Photosynthesis takes place in two sequential stages: The light-dependent reactions; The light-independent reactions, or Calvin Cycle.
What do plants give off during photosynthesis?
During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose.
Which substance is used up in photosynthesis?
In photosynthesis, water and carbon dioxide are used as raw materials to produce glucose and release out oxygen.
What are the 3 metabolic pathways?
There are three metabolic pathways that provide our muscles with energy: the phosphagen pathway, the glycolytic pathway, and the oxidative pathway.
What are the four metabolic pathways?
Let us now review the roles of the major pathways of metabolism and the principal sites for their control:
- Glycolysis. …
- Citric acid cycle and oxidative phosphorylation. …
- Pentose phosphate pathway. …
- Gluconeogenesis. …
- Glycogen synthesis and degradation.
What are the 5 metabolic processes?
In humans, the most important metabolic pathways are: glycolysis – glucose oxidation in order to obtain ATP. citric acid cycle (Krebs’ cycle) – acetyl-CoA oxidation in order to obtain GTP and valuable intermediates. oxidative phosphorylation – disposal of the electrons released by glycolysis and citric acid cycle.
What is the role of light in photosynthesis?
The process of photosynthesis occurs when green plants use the energy of light to convert carbon dioxide (CO2) and water (H2O) into carbohydrates. Light energy is absorbed by chlorophyll, a photosynthetic pigment of the plant, while air containing carbon dioxide and oxygen enters the plant through the leaf stomata.
