WebOct 23, 2024 · Photosynthesis requires two types of photosynthetic units, referred to as photosystem I and photosystem II. Their reaction centers can be differentiated as they are related to proteins in a way that induces a slight difference in their absorption spectra. Normally, chlorophyll a has a strong absorption peak at about 660 nm. WebA) All of the sunlight that hits the atmosphere is used for photosynthesis. B) Only the highest energy wavelengths are used for photosynthesis. C) All of the visible light is used for photosynthesis. D) Only the red, blue, and violet wavelengths of visible light are used for photosynthesis.
7.3: The Light-Dependent Reactions of Photosynthesis
WebAbsorbance of a 1 M solution so it can be measured easily by the obvious - reading Absorbance of a 1 M solution. However, for substances with strong absorbance, the Absorbance of a l M solution is too great to read in an analytical instrument. In this case a standard curve is produced by measuring Absorbance of a number of dilute solutions, … WebApr 5, 2014 · The photosynthetic pigments are necessary compounds for energy absorption and conversion in phototrophic organisms. ... At concentrations of 0.5% and 1% of detergent the yield was lower than the control at the lowest 2 or 3 intensities of irradiance; however, at increased irradiances the yield of treated cultures was … software donated for public use

WebIf the spinach leaves are placed under blue or red light, the rate of photosynthesis will be faster than green light because chlorophyll a and b as well as several types of carotenoids are present in the spinach. This causes an absorption of energy from red and blue wavelengths which is used in photosynthesis. slowdown video online
