What is the unit of hundreds of chlorophyll molecules that trap the energy of sunlight?
The unit of hundreds of chlorophyll molecules that trap the energy of sunlight is typically referred to as a "photosystem." In plants, these photosystems, primarily Photosystem I and Photosystem II, contain clusters of chlorophyll molecules that work together to capture light energy during photosynthesis.
How do you compare the different roles of photosystem 1 and photosystem 2 in photosynthesis?
The structure of photosystem I in a cyanobacterium ("blue-green alga") has been completely worked out. It probably closely resembles that of plants as well. It is a homotrimer with each subunit in the trimer containing: * 12 different protein molecules bound to * 96 molecules of chlorophyll a ** 2 molecules of the reaction center chlorophyll P700 ** 4 accessory molecules closely associated with them ** 90 molecules that serve as antenna pigments * 22 carotenoid molecules * 4 lipid molecules * 3 clusters of Fe4S4 * 2 phylloquinones Photosystem II is also a complex of * > 20 different protein molecules bound to * 50 or more chlorophyll a molecules ** 2 molecules of the reaction center chlorophyll P680 ** 2 accessory molecules close to them ** 2 molecules of pheophytin (chlorophyll without the Mg++) ** the remaining molecules of chlorophyll a serve as antenna pigments. * some half dozen carotenoid molecules. These also serve as antenna pigments. * 2 molecules of plastoquinoneSource: http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/L/LightReactions.html
Energy is pass around chlorophyll molecules until it reaches a specific chlorophyll molecule called?
Chlorophyll is arranged in clusters called photosystem. It is like a upside down cone. It is made from secondary chlorophyll pigments surrounding a reaction center(primary pigment) at the tip of the cone. The secondary pigments absorb the light energy and pass it to the reaction center.
What are the clusters of photosystems?
The two clusters of photosystems in plants are Photosystem I (PSI) and Photosystem II (PSII). PSII functions first in the photosynthetic electron transport chain, followed by PSI, and they work together to absorb light energy and carry out the reactions of photosynthesis.
What is a photosystem?
A photosystem is a cluster of pigments and proteins in the thylakoid membrane of chloroplasts, involved in the light-dependent reactions of photosynthesis. It captures light energy and converts it into chemical energy, which is used to drive the production of ATP and NADPH.

Clusters of pigment molecules?
Clusters of pigment molecules are aggregates of pigments that come together in a specific spatial arrangement. These clusters play a key role in light absorption and energy transfer processes in photosynthetic organisms, such as plants and algae. By organizing pigment molecules in clusters, these organisms can efficiently capture light energy for photosynthesis.
What is a photosystem?
A photosystem is a cluster of pigments and proteins in the thylakoid membrane of chloroplasts, involved in the light-dependent reactions of photosynthesis. It captures light energy and converts it into chemical energy, which is used to drive the production of ATP and NADPH.
Electron transport chains help move excited electrons along in photosystem II clusters?
true
What are cluster of chlorophyll called?
Photosystems Photosystems
What do you call the clusters of chlorophyll molecules that capture light energy?
They are called photosystems. Photosystems are groups of chlorophyll molecules and associated proteins that work together to absorb and transfer light energy during the process of photosynthesis.
Are photosystems clusters of chlorophyll and proteins?
Yes, photosystems are clusters of chlorophyll and other pigments, as well as proteins, that are essential components of the light-dependent reactions in photosynthesis. They work together to absorb light energy and initiate the electron transport chain that drives the production of ATP and NADPH.
Are electrons are energized twice during photosynthesis?
Yes because there are two photosystems (clusters of chlorophyll) which is where the sunlight is absorbed from, the electrons are energized at both times because sunlight contains photons which are the molecules that energize the electrons in the first place
