when chlorophyll runs out of electrons where does it find new ones?
The light dependent reactions use energy from sunlight to produce what 3 things?
Chlorophyll never runs out of electrons because the thylakoid membrane always gives new electrons to replace the lost electrons. Light dependent reactions use energy from sunlight to produce: oxygen, NADPH, and ATP. *Am not 100 percent sure about the answer. I am a student too.
When chlorophyll runs out of electrons during photosynthesis, it obtains new ones by splitting water molecules. Water molecules contain two hydrogen atoms and one oxygen atom. During the light-dependent reactions of photosynthesis, the water molecules are split, releasing oxygen into the atmosphere, and providing the necessary supply of electrons to the chlorophyll.
The three things produced during the light-dependent reactions of photosynthesis are:
1. ATP (Adenosine Triphosphate): ATP is a molecule that stores and transfers energy within cells. It is produced during the phosphorylation of ADP (Adenosine Diphosphate), using the energy from sunlight.
2. NADPH (Nicotinamide Adenine Dinucleotide Phosphate): NADPH is a coenzyme that carries high-energy electrons. It is also produced during the light-dependent reactions, and it is essential for the subsequent reactions of the Calvin cycle.
3. Oxygen: As mentioned earlier, water molecules are split during the light-dependent reactions. This process releases oxygen as a byproduct, which is then released into the atmosphere as a waste product of photosynthesis.
When chlorophyll runs out of electrons, it obtains new electrons through a process called photosynthesis. During photosynthesis, chlorophyll molecules capture energy from sunlight, which is used to split water molecules into oxygen and hydrogen ions. The chlorophyll then uses these newly released electrons from the hydrogen ions to replace the ones that were lost.
Now, moving on to your second question, the light-dependent reactions in photosynthesis use energy from sunlight to produce three things:
1. ATP (adenosine triphosphate): It is a molecule that stores and transfers energy within cells. The energy from sunlight is used to convert ADP (adenosine diphosphate) into ATP, providing energy for cellular activities.
2. NADPH (nicotinamide adenine dinucleotide phosphate): It is an electron carrier molecule that is vital for storing and transferring high-energy electrons. Similar to ATP, the energy from sunlight is used to convert NADP+ (nicotinamide adenine dinucleotide phosphate) into NADPH.
3. Oxygen (O2): As mentioned earlier, water molecules are split during the light-dependent reactions. As a result, oxygen molecules are produced as a byproduct and released into the atmosphere. Oxygen is essential for supporting aerobic respiration in organisms, including humans.
So, in summary, the light-dependent reactions in photosynthesis use sunlight energy to produce ATP, NADPH, and oxygen.
