Which wavelengths of light drive the highest rate of photosynthesis?
The best wavelengths of visible light for photosynthesis fall within the blue range (425–450 nm) and red range (600–700 nm). Therefore, the best light sources for photosynthesis should ideally emit light in the blue and red ranges.

What are the two major light energy that drive photosynthesis?
Photosynthesis takes place in two distinct stages. In the light reactions, energy from sunlight drives the synthesis of ATP and NADPH, coupled to the formation of O2 from H2O. In the dark reactions, so named because they do not require sunlight, the ATP and NADPH produced by the light reactions drive glucose synthesis.

Which wavelengths of light drive photosynthesis worksheet?
Chlorophyll absorbs light most effectively in the blue to violet and orange to red range. Since violet wavelengths have the most energy (due to their shorter wavelengths) they can provide the maximum energy for photosynthesis. 9.

Which wavelength of light has the highest rate of photosynthesis?
The best wavelengths of visible light for photosynthesis fall within the blue range (425–450 nm) and red range (600–700 nm). Therefore, the best light sources for photosynthesis should ideally emit light in the blue and red ranges.

What wavelength increases the rate of photosynthesis?
PSI absorbs energy most efficiently at 700 nm and PSII at 680 nm. Light with a higher proportion of energy concentrated in these wavelengths will produce a higher rate of photosynthesis.

What are the 2 energies in photosynthesis?
In photosynthesis, solar energy is harvested and converted to chemical energy in the form of glucose using water and carbon dioxide. Oxygen is released as a byproduct.

What are the two 2 major processes of photosynthesis?
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.

What type of energy drives photosynthesis?
The source of energy that drives photosynthesis is sunlight or light energy. The sun produces energy that travels to Earth and is absorbed by chlorophyll inside the chloroplast of plants. Plants harness that light energy and convert it to chemical energy stored in the bonds of glucose molecules.

What are the 2 main types of light absorbing molecules found in plants?
In the light-dependent reactions, energy absorbed by sunlight is stored by two types of energy-carrier molecules: ATP and NADPH. The energy that these molecules carry is stored in a bond that holds a single atom to the molecule. For ATP, it is a phosphate atom, and for NADPH, it is a hydrogen atom.

What wavelengths of light drive photosynthesis?
Visible light ranges from low blue to far-red light and is described as the wavelengths between 380 nm and 750 nm, although this varies between individuals. The region between 400 nm and 700 nm is what plants use to drive photosynthesis and is typically referred to as Photosynthetically Active Radiation (PAR).

What wavelength of light listed below would be least effective in driving photosynthesis?
The wavelength of green light is thought to be the least efficient for photosynthesis. If the plants are exposed to green wavelengths during photosynthesis, the rate of photosynthesis will be the slowest. This is due to the presence of chlorophyll, a green pigment.
