What characteristic of the light-absorbing regions of chlorophylls and carotenoids most likely accounts for the ability of these molecules to absorb light? A. The presence of aldehyde side-groups B. Long hydrocarbon chain C. Ringed structures D. The p ...
Along with green chlorophyll, most leaves also contain yellow, orange and red-orange pigments celled carotenoids. Trees don't need light to make carotenoids. Botanists call them "helper pigments," because carotenoids absorb some sunlight and (nicely) pass the energy along to chlorophyll. We don'...
Which of these pigments absorb photons that strike plant leaves? A. Chlorophyll a B. Chlorophyll b C. Carotenoids D. All of these E. None of these Which form of photosynthesis is the most energy-efficient? a) C3 b) C4 c) CAM d) All forms of photosynthesis are energy efficient. What ...
On the other end of the spectrum from infants, lutein makes up 34 percent of the carotenoids in the brain of those age 100 or older. Multiple elementary studies have linked a lutein-rich brain to a variety of cognitive functions includingverbal fluency, executive function, memory and recall. ...
That’s when vivid yellow xanthophylls, orange carotenoids and, due to a different process, red and purple anthocyanins emerge. Orange is found in leaves with lots of beta-carotene, a compound that absorbs blue and green light and reflects yellow and red light, giving the leaves their orange ...
Xanthophyll and Carotenoids are responsible for the bright yellows and oranges ofautumn leaves. These are the same substances that make acarrotorange andcornyellow. Carotenoids and Xanthophyll are present in leaves at all times during the growing season (they help absorb sunlight) but are hidden by...

We used the simple native system (bacterial complex LH2/3), including two types of pigments (BChl and carotenoids) and polypeptides, which are able to absorb the energy of a quanta of sunlight, convert it into excitation energy, and then dissipate the latter in the form of radiant energy ...
