Photosystems are the light-harvesting units of the thylakoid membrane.Each photosystem is a complex of proteins and other kinds of moleculea and includes an antenna consisting of a few hundred pigment molecules. When any antenna molecule absorbs a photon, the energy is transmitted from pigment molecule to pigment molecule until it reaches a particular chlorophyll a.Only this chlorophyll molecule is the reaction center and the first light-driven chemical reaction of photosynthesis occures.
What else can I help you with?
Why is the dark reactions called a cycle?
RuBP made during the dark reaction is used to start the reaction again. novanet.
How many molecules of G3P made during the Calvin cycle are required to produce one molecule of glucose?
Six molecules of G3P are required to produce one molecule of glucose during the Calvin cycle.
Which molecule is made in the nucleus but exits to function in the cytoplasm?
mRNA (messenger RNA) is the molecule that is made in the nucleus during transcription, carrying the genetic information from DNA, and then exits to function in the cytoplasm during translation to direct protein synthesis.
Are ATP molecules made during the light-independent reactions of photosynthesis?
No, ATP molecules are not directly made during the light-independent reactions of photosynthesis (Calvin cycle). ATP is produced during the light-dependent reactions (Light reactions) of photosynthesis when light energy is used to convert ADP and inorganic phosphate into ATP. The ATP produced in the light reactions is then utilized as an energy source during the Calvin cycle to drive the conversion of carbon dioxide into glucose.
When during photosynthesis is glucose made?
Glucose is made during the light-independent reactions, also known as the Calvin cycle, of photosynthesis. This process converts carbon dioxide and other molecules into glucose using the energy stored in ATP and NADPH molecules generated during the light-dependent reactions.
What molecule is made during the light dependent reactions?
Glucose

How did Dalton know how many atoms were in a molecule?
Dalton determined the relative atomic masses of elements based on their chemical reactions. By analyzing the mass ratios involved in reactions, he was able to propose that all matter is made up of indivisible atoms, and he deduced the number of atoms in a molecule based on these atomic ratios and consistent patterns in reactions.
If molecules are made of atoms.And molecules are use in chemical reaction to make new elements. Does the elements in atoms also changes?
Molocules do not make new elements. Elements only change during atomic reactions, primarily nuclear fusion in stars. The atoms in a molecule are always the same, during chemical reactions they are only being rearranged. The oxygen you breathe in and the carbon dioxide that you breathe out, for example, are made of the same oxygen atoms.
What is a sugar molecule made during photosynthesis?
Glucose is the sugar molecule made during photosynthesis. It is produced from the combination of carbon dioxide and water in the presence of sunlight, using the energy obtained from sunlight to drive the chemical reaction.
