What else can I help you with?
Electrons are excited in photosystem 1 what do these electrons combine with in order to produce an energy-carrying molecule?
NADP+
What electrons excited by sunlight in Photosystem are replaced with?
In Photosystem II, electrons excited by sunlight are replaced by electrons derived from the splitting of water molecules (photolysis). This process releases oxygen as a byproduct and provides the necessary electrons to replenish those lost by the chlorophyll when it absorbs light energy. In Photosystem I, the excited electrons are eventually transferred to NADP+, forming NADPH, which is crucial for the Calvin cycle in photosynthesis.
What heppens when light strikes green plant pigments?
electrons become excited
What causes the electrons to become excited and move into the electron transport chain?
Electrons become excited in the electron transport chain due to the energy input from electron carrier molecules like NADH and FADH2. These electron carriers donate the electrons to the proteins in the chain, creating a flow of electrons that drives the production of ATP.
What makes an elements electrons in an excited state?
An element's electrons can be in an excited state when they absorb energy from an external source, such as heat or light. This added energy causes the electrons to move to higher energy levels further from the nucleus. As the electrons return to their original energy levels, they release this extra energy in the form of light or heat.
When sunlight excited electrons in chlorophyll how do the electrons change?
the electrons gain a huge amount of energy
What high-energy molecule do excited electrons generate?
ATP

What is the electron carrier molecule when carrying excited electrons it becomes NADPH?
NADP

What is the first most immediate thing that happens when light strikes a chlorophyll molecule?
When light strikes a chlorophyll molecule, electrons in the chloroplast get excited.
What heppens when light strikes green plant pigments?
electrons become excited
Where do electrons get there energy from photostem 2?
Electrons in photosystem II get their energy from sunlight. When photons from sunlight are absorbed by the chlorophyll molecules in the photosystem, the energy is transferred to electrons, allowing them to become excited and drive the process of photosynthesis.
What is the first most immediate thing that happens when light strikes chlorophyl molecule?
When light strikes a chlorophyll molecule, electrons in the chloroplast get excited.
What picks up energized electrons from reactions in the thylakoids of plants during photosynthesis?
The molecule that picks up energized electrons in the thylakoid membranes during photosynthesis is called NADP+ (nicotinamide adenine dinucleotide phosphate). It accepts the electrons and is reduced to NADPH, which then carries the electrons to the Calvin cycle for the production of sugars.
Are excited electrons from the acceptor molecule sent to the electron transport chain?
Yes, excited electrons from the acceptor molecule are sent to the electron transport chain. This process allows the electrons to move through a series of protein complexes in the inner mitochondrial membrane, ultimately leading to the generation of ATP through oxidative phosphorylation.
Summarize how photosynthetic organisms capture the energy in sunlight?
The light-dependent portion of photosynthesis is carried out by two consecutive photosystems (photosystem I and photosystem II) in the thylakoid membrane of the chloroplasts. The photosystems are driven by the excited chlorophyll molecules.To begin photosynthesis, the chlorophyll molecule in photosystem II is excited by sunlight and the energy produced helps to break down a water molecule (H2O) into ½O2 (with electrons removed) and 2H+. The removed electrons are excited by the light energy. When the electrons prepare to come to their rest state, they go through an oxidative phosphorylation process and produces an ATP molecule.As the electrons are coming to a resting state, they are excited again in photosystem I and raised to a even higher energy state. The excited electrons are then used to produce NADP+ + H+. The highly energetic NADPH molecule is then fed into the Calvin Cycle to conduct carbon fixation.
