What is photosynthesis in biology IB?
Photosynthesis is the production of carbon compounds in cells using light energy. Oxygen is produced in photosynthesis from the photolysis of water. Energy is needed to produce carbohydrates and other carbon compounds from carbon dioxide.
How does photosynthesis produce glucose IB Biology?
Photosynthesis involves the conversion of light energy to chemical energy and consists of a light-dependent reaction (requires light energy) and a light-independent reaction (does not require light energy). As shown in Figure 1 below, carbon dioxide and water are used to produce glucose and oxygen.
What is photosynthesis bio ninja?
Photosynthesis is a two step process: The light dependent reactions convert light energy from the Sun into chemical energy (ATP) The light independent reactions use the chemical energy to synthesise organic compounds (e.g. carbohydrates)
What is aerobic respiration in biology?
A chemical process in which oxygen is used to make energy from carbohydrates (sugars). Also called aerobic metabolism, cell respiration, and oxidative metabolism.
How do plants capture and use light in photosynthesis IB?
Only green parts of the plants, particularly leaves, entrap sunlight as green parts contain a pigment, called chlorophyll. Chlorophyll is capable of entrapping sunlight. Thus non-green plants, which lack chlorophyll, can’t entrap sunlight.
How water is used in photosynthesis?
In the process of photosynthesis, water provides the electron that binds the hydrogen atom (of a water molecule) to the carbon (of carbon dioxide) to give sugar (glucose).
What is the similarities of photosynthesis and respiration?
Both photosynthesis and respiration involve the conversion of energy from one form to another through a series of biochemical reactions. Both processes use and produce ATP in reactions that are carried out on membranes and are controlled by enzymes.
