2016年11月23日 · As light intensity increases, so does the rate of photosynthesis, up until a point. Photosynthesis, specifically the light reactions, require light to occur. The light's photons excite the electrons in the pigments of the photosystems which activates the light reactions portion of photosynthesis. The more light there is, the more photosystems in the thylakoid membrane …

2018年7月10日 · light does not affect cellular respiration in plants Cellular respiration does not depend on light. Photosynthesis does depend on light. Cellular respiration takes place during the daytime and during the night time. Some plants may go into a form of hibernation during the winter when the amount of light during the day is less. The reduction of plant growth and …

2015年10月24日 · Photosynthesis first, Cellular Respiration second. Photosynthesis: the intensity of the light being absorbed by the chloroplasts the concentration and availability of CO2 (Carbon Dioxide) the temperature Cellular Respiration the availability of oxygen (determines whether or not fermentation will be used) the availability and amount of glucose (the food being broken down) …

2015年1月2日 · Light provides energy for the synthesis of glucose from carbon dioxide and water during photosynthesis. Photosynthesis is a photo-chemical reaction involving 2 main steps, i.e. Light reaction or Hill’s reaction and Dark reaction or Blackmann’s reaction. Light reaction occurs in presence of light. Dark reaction can occur in absence of light but is dependent upon the end …

2018年6月10日 · Well we need to consider other factors as well... Consider the photosynthesis equation: 6CO_2(g)+6H_2O(l)stackrel("sunlight")stackrel("chlorophyll")->C_6H_12O_6(aq)+6O_2(g) Usually, increase the carbon dioxide content would increase the rate of reaction right? But also to a certain extent, where we need to consider other necessities, …

2016年1月12日 · The process of photosynthesis produces oxygen. The overall equation for photosynthesis is: 6CO_2 + 6H_2O -> C_6H_12O_6 + 6O_2 The oxygen created during photosynthesis is created when light energy is used to split water molecules. This is called the light reaction . 2H_2O -> 2H_2 + O_2 Here is a video which discusses the process of …

2015年5月9日 · If the frequency of electromagnetic waves is higher than the extraction threshold of the metal and electrons are emitted from the metal surface, then an increase of light intensity will result in a proportional increase of electrical current of the electrical circuit where the emitted electrons are conveyed. This is simply explained by the photon model of light. In that model an ...

2014年9月7日 · Leaves absorb light to give their enzymes enough energy to perform photosynthesis. Two types of chemical are used to absorb the light, called chlorophyll and carotenoids. As the graph shows, chlorophyll absorbs red and blue light, while carotenoids absorb blue and blue/green light. So the colour of leaves is light green, since that's the only colour not …

2018年8月6日 · Carbon fixation is the first step out of three in the Calvin Cycle (the light-independent reactions). In carbon fixation, carbon dioxide is fixed from being an inorganic molecule to an organic molecule. Firstly Carbon dioxide reacts with RUBP this reaction is catalyzed by the enzyme rubisco this produces a short-lived molecule that spontaneously …

2016年5月27日 · Any frequency outside of the range required by chlorophyll for energy conversion will result in a loss of photosynthesis activity. Chlorophyll (actually the pigments of related cyanobacteria and chloroplasts) can only use certain frequencies of light to provide the energy needed for photosynthesis. Thus, any frequencies outside of a relatively narrow band …
