According to some studies if you eat more fruit and vegetables which are rich with vitamin C, which in turn accelerates your metabolism, removes nicotine from your bloodstream faster.
These are also pigments with colors ranging from red to yellow. Carotenoids absorb light most strongly in the blue portion of the spectrum. They thus enable the chloroplast to trap a larger fraction of the radiant energy falling on it. Carotenoids are often the major pigments in flowers and fruits.hese are also pigments with colors ranging from red to yellow.

Stages of photosynthesis. When chlorophyll a absorbs light energy, an electron gains energy and is 'excited'. The excited electron is transferred to another molecule (called a primary electron acceptor). The chlorophyll molecule is oxidized (loss of electron) and has a positive charge.hen light energy is absorbed by a chlorophyll molecule its electrons gain energy and move to higher energy levels in the molecule (photoexcitation). Sufficient energy ionises the molecule, with the electron being 'freed' leaving a positively charged chlorophyll ion. This is called photoionisation.
