解析 1. Chlorophyll is a pigment found in chloroplasts within plant cells. It is responsible for transferring energy from sunlight into chemical energy. 2. Carbon dioxide is another raw material required for phot
A) Absorbing sunlight. 在光合作用中,叶绿素的主要功能是吸收光能。以下是逐项分析:1. **选项A(吸收阳光)**:叶绿素作为光合色素,其核心作用是捕获太阳光能(尤其是红光和蓝紫光),并将其转化为化学能供暗反应使用。此过程发生于光反应阶段,与光合作用直接相关。2. **选项B(提供营养)**:植物通过根系吸收养分,...
2001. Peridinin-chlorophyll a-protein is not implicated in the photosynthesis rhythm of the dinoflagellate Gonyaulax despite circadian regulation of its trans- lation. Biol. Rhythm Res. 32:579-94Le, Q.H., Jovine, R., Markovic, P., Morse, D., 2001. Peridinin-chlorophyll a-protein is ...
Chlorophyll is the primary pigment used for photosynthesis and gives plants their green color, according to science education siteNature Education. Chlorophyll absorbs red and blue light and reflects green light. Chlorophyll is a large molecule and takes a lot of resources to make; as such, it br...
Photosynthesis is a biochemical process that is carried out by photoautotrophs to convert light energy into potential energy. It occurs in the chloroplast with the help of the photosynthetic pigment named chlorophyll (present in the thylakoid). Some examples of photoautotrophs ...
Why do plants need mitochondria even though they use photosynthesis to get energy? What's cellular respiration? Explain how the absorption spectrum of chlorophyll relates to photosynthetic productivity. During glycolysis, the glucose is broken down to begin cellular respiration. What other ...
除了Toc/Tic复合物 参与叶绿体蛋白输入外, 核编码叶绿体蛋白的输入还 可通过其它方式实现.一些类囊体功能蛋白, 如形成 叶绿素复合体的蛋白 (light-harvesting chlorophyll, Lhc)被基质叶绿体信号识别颗粒(cpSRP43/54)所识 别, 进而调节蛋白插入内膜.研究表明, Lhc的完全插 入需要膜定位蛋白 ALB3 的协助 (Bellafiore...
Photosynthesis Photosynthetic performance was measured using a PAM-2000 chlorophyll fluorometer (Walz GmbH, Effeltrich, Germany) at 12 ± 1°C (Rautenberger et al. 2009). Minimum (F0) and maximum fluorescence (Fm) were measured after 5 min of dark adaptation and maximum PSII-quantum yield...
(for 0.5, 1, 2 h) at the light intensity of 100 µmolm-2 s-1. Total protein was extracted and analyzed by western blot. Chlorophyll a/b binding protein CP29 (Lhcb4) and cytosolic UDP-glucose pyrophosphorylase (UGP) were used as controls. EX1-GFP, Lhcb4, and UGPase were ...
What is the role of chlorophyll during photosynthesis? What substances are used during photosynthesis? What substances are produced during photosynthesis? How does photosynthesis work? What is the function of light energy during the photosynthesis process in plants?
