A. chlorophyll B. carotene C. xanthophyll D. anthocyanin 相关知识点: 试题来源: 解析 A。本题考查光合作用中的绿色色素。植物中的绿色色素是叶绿素,有助于光合作用。选项 B 胡萝卜素、选项 C 叶黄素、选项 D 花青素都不是主要进行光合作用的色素。所以答案是 A。反馈...
A. chlorophyll B. melanin C. keratin D. hemoglobin 相关知识点: 试题来源: 解析 A。解析:本题考查与光合作用相关的植物中的色素。选项B“melanin”是黑色素,存在于动物皮肤等部位,与植物光合作用无关;选项C“keratin”是角蛋白,主要存在于毛发、指甲等部位,与植物无关;选项D“hemoglobin”是血红蛋白,存在于...
Chlorophyll complex supplements are considered to be more beneficial than simply cooking and eating green vegetables as prolonged cooking reduces the amount of chlorophyll present. The supplements are usually made from alfalfa, which contains a very high level of the pigment and is also readily grown...
Chlorophyll A and B are the two major pigments, involved in photosynthesis. Chlorophyll A is the primary pigment of photosynthesis, trapping the light energy and emitting highenergy electrons into the two photosystems P680 and P700. Chlorophyll B is the accessory pigment, passing the trapped energy...

It occurs in the chloroplasts of plant cells and involves a series of chemical reactions. In the presence of sunlight, chlorophyll (a pigment found in chloroplasts) captures energy and converts it into chemical energy, which is used to convert carbon dioxide and water into glucose. Oxygen is ...

The pattern of AtPHT4;4 localization was very similar to that of TIC40, which is an envelope membrane marker, but not light-harvesting chlorophyll protein 2 (LHC2), which is a thylakoid membrane marker (Fig. 3c middle and lower, respectively). Na+/phosphate transport 4 3 2 1 0 15 Δ...
Chlorophyll a and b have been reported to be synthesized in sea slugs’ cells by some authors [25,26], while others have found no evidence supporting this synthesis [27]. Even though it is not clear if pigments are broken down or synthesized in the animal cells, they are still present ...
Pigment profiles and content compositions were measured at different experimental stages during the culture. The pigments of Nephroselmis sp. include chlorophyll a (chl a), chlorophyll b (chl b), β-carotene, lycopene, lutein, zeaxanthin, antheraxanthin, violaxanthin, all-trans-neoxanthin, cis-neoxa...
