For photosynthesis in green plants, the electron donor for the light dependent reaction is water.
What are the events during light dependent reaction?During photosynthesis, the light dependent reactions occur in the thylakoids. The electrons are provided by the breakdown of water.Within the thylakoid membrane, chlorophyll captures energy from the sun in the form of photons and breakdown the water molecules producing energy in the form of ATP and NADPH.Chlorophyll pigment is present in both Photosystem I (PS I) and Photosystem II (PS II) which are also known as light harvesting complexes.Light reactions begin with the excitation of electron in chlorophyll of PS II by sunlight. This excited electron leaves the chlorophyll and travels via electron transport chain.To fill the void created by the loss of an electron, PS II drives an electron by splitting of water molecule.Learn more about light-dependent reaction here:

How is information from a signal molecule present outside the cell elicits intracellular response? Explain with suitable example. What features are exhibited by signal transduction?
The information from a signal molecule present outside the cell elicits intercellular response when the G protein coupled receptors interact with the wide variety of molecules on the outer surface of the cells.
G Proteins are the specialized proteins having the ability to bind GTP and GDP and is of three units called Alpha, Beta and Gamma subunits which together formed G proteins.
When G protein is activated it will bind GTP and each receptor binds in lock and key method and binding result into conformational change which will trigger a complex chain of events influencing different cell function.
Features exhibited by Signal Transduction System are:
1. Specificity- Signal molecules fits binding site on its complementary receptor. Other signal do not fit
2. Amplification- When enzymes activates enzymes, the number of affected molecules increases.
3. Desensitization- Receptor activation triggers a feedback circuit that shuts off the receptor or removes it from the cell surface.
4. Integration - When two signals have opposite effects on a metabolic characteristics outcome results from the integrated input from both the receptor.

Disease that is characterized as having lack of energy and protein is called?
Answer:
Sounds closest to: Kwashiorkor
Explanation:
Kwashiorkor is a disease brought on by severe protein malnourishment. In Kwashiorkor, extended breastfeeding and late, insufficient weaning lead to low calorie intakes but significantly superior biological value. As a result, a kid with kwashiorkor will likely experience compromised organ function and development. Sudden outbreaks of diseases like the measles, gastroenteritis, or pneumonia exacerbate the issue by increasing needs while maintaining low intakes. The kid may exhibit oedema of the face and lower limbs, failure to grow, anorexia, diarrhea, lethargy, dermatosis, flaky-looking skin, scant, soft, and thin hair, angular stomatitis, cheilosis, and anemia as a result of this scenario.
This is a bit similar to Marasmus.
But there is a difference.
But ⇒ how does kwashiorkor and marasmus differ?
Kwashiorkor is predominantly a protein shortage, despite adequate calorie intake. When a youngster is weaned off of protein-rich breast milk, it frequently happens. The patient will show signs of oedema, an enlarged abdomen, and other conditions.
Marasmus is a total energy shortage that causes a body weight that is at least 60% below normal. The victim will only be malnourished.

after it is released a mature egg travels by the means of
Answer:
Muscle Contractions
*EDUCATIONAL PURPOSES*
Ovulation Process:
The pituitary gland, located in your brain, releases a hormone once every month. This hormone instructs the ovaries to create many follicles, which are fluid-filled cysts. The hormone oestrogen is secreted by the growing follicles. In order to prepare for pregnancy, oestrogen causes the uterine membrane to thicken.
The follicles cease developing on day seven of your cycle, with the exception of one. This follicle keeps expanding and nourishes an oocyte (egg) that is developing within.
On day 12, a surge of oestrogen is released into the bloodstream by the developing follicle. Your blood carries the oestrogen along. The pituitary gland in your brain releases luteinizing hormone in response to the oestrogen reaching it. This hormone causes a quick growth spike in the follicle.
The egg within the follicle separates from the follicle just before ovulation. The neighboring fallopian tube begins to migrate toward and around the follicle as the follicle begins to produce chemicals.
The egg and fluid are ejected into the abdominal cavity when the follicle expands to the point of breaking open.
Fimbriae, or tiny finger-like projections at the termination of the fallopian tube, move over the ruptured follicle and seize the egg.
The egg is moved to the fallopian tube's opening. Muscle contractions push the egg gently towards the direction of the uterus once it has entered the fallopian tube's walls.
Either sperm will contact the egg as it travels down the fallopian tube, resulting in fertilization, or the egg will arrive in the uterus unfertilized and be reabsorbed into the body.
Conception Process:
A woman must fertilize her egg within the 12 to 24 hours following ovulation if she wants to get pregnant.
The surge of oestrogen right before ovulation also creates the protein-rich transparent jelly that covers the vagina during intercourse within the neck of the uterus (the cervix). Thus, the vagina became acidic (which prevents thrush and other infections). Sperm can survive in this environment as well. Rapidly moving sperm swim up and into the cervix, where they can live for up to five days in the mucus until an egg is produced.
The fallopian tube might grab the egg because it is wrapped in sticky cells when it is released after ovulation. The sperm begin to break down the adhesive cells when they encounter the egg in the fallopian tube. While only one sperm is required to create a baby, numerous are required to cling to the egg's membrane and outer shell before one may penetrate and fertilize it.
After fertilization, substances are produced to prevent the entry of more sperm before the egg and sperm swiftly combine and split to form an embryo.
The fertilized egg continues to divide and move toward the uterus throughout the course of the following four to five days.
The burst follicle (now known as the corpus luteum), which releases the hormone progesterone into your bloodstream, primes the uterus for the egg to implant.
The pregnancy is sending an increasingly potent signal to the ovary to prolong and boost the production of progesterone, which the pregnancy needs to live, while it develops and installs itself into the mother's uterine lining and blood vessels.

What if the light intensity was 1000, what do you predict the ATP production percentage would be?
Main Answer:
ATP Production will not change as change in wavelength because it depends on no. of photons striking the surface means intensity of light.
Explanation:
ATP Production is depend upon intensity of light and not on wavelength of light.
No. of electrons involved in ATP Production depends on intensity of light.
If the light intensity is about 1000, then it will not positively affect ATP synthesis. Because enzymes do not function properly, it may harm photosynthesis.
What Role Does Light Play in Photosynthesis?The sunlight acts as a catalyst for the photosynthesis process and promotes the production of ATP (energy), glucose, and oxygen. The sunlight breaks the water molecule and forms the electron. This process is called photolysis of water and takes place in the thylakoid membrane. This occurs in the thylakoid membrane's Photosystem II (PS II).
Electrons move from photosystem II to photosystem I. The movement of the electron generates the proton gradient across the membrane. Due to the higher protons inside the lumen of the thylakoid, these move to the outer side, and as a result, ATP synthase makes ATP. If such a bright light shines on these complexes, the enzymes will stop working and ATP synthesis will suffer.
Hence, an increase in light intensity would have a negative impact on ATP production.
