Photosynthesis
This category is for questions about the chemical process in which autotrophic organisms use sunlight, carbon dioxide and water to make glucose, water and oxygen. This process is vital to life and is of great importance in biology.

How would photosynthesis be affected if there were a shortage of NADP plus in the cells of plants?
ok, so, NADP+ accepts and holds 2 high energy electrons along with a hydrogen ion. so if there was a shortage it wouldn't be able to run through the cycle of photosynthesis.
What do plants produce during the first stage of photosynthesis?
They produce oxygen gas during the light reactions.
What happens during light reactions in photosynthesis?
light strikes photosystem 2, exciting the electrons. The electron come from a water molecule that has been split into hydrogen and oxygen. That is the first reactant (water), and Oxygen gas is given off as the first product. The excited electrons then travel down a short electron transport chain, and while doing so they pump H+ molecules (hydrogen molecules) into the inner thylakoid space across the thylakoid membrane from the stroma. The electrons are then passed, at the end of the transport chain, to photosystem 1, where they are re-excited by light. The electrons are passed down another short electron transport chain, which pumps a few more H+ into the thylakoid space, then the electrons get passed to a molecule of NADP+, which is reduced to NADPH. NADPH is a product, NADP+ a reactant. The H+ in the thylakoid then diffuse back into the stroma through a molecule of ATP Synthase that is a channel through the memebrane of the thylakoid. As they pass through the ATP synthase, the H+ make the ATP Synthase go into it's active conformation so it is able to turn ADP into ATP. ADP is a reactant, ATP is a product. To sum it all up, H20, NADP+, and ADP are reactants, and oxygen, NADPH, and ATP are products
Why can mushrooms not photosynthesis with explanation?
they do not contain chlorophyll, so they cannot absorb light energy for phtosynthesis
Can a peony go through photosynthesis?
All plants photosynthesis (well the green portions in any case).
Sunflower is the common name for Helianthus (Helios Greek for Sun and anthus = flower).
The actual flowering portion or flower (disc and ray florets) do not photosynthesis as they contains no chlorophyll.
Is air needed in photosynthesis?
No,photosynthesis is only making of food
Carbon dioxide is needed for photosynthesis. It is the carbon sourse
What pigment absorbs when photosynthesis begins?
Chlorophyll is the green pigments in plants, algae, and cyanobacteria that absorbs energy from light during photosynthesis. Its main function is to absorb light energy and pass it onto the photosystems in order to generate the energy needed to continue photosynthesis. The type of chlorophyll (for example, chlorophyll a) varies between photosynthetic organisms.
How do plants carry out the process of nutrition?
Plants are autotrophs and produce, or synthesize, their own nutrition (glucose) by using the energy contained in sunlight. Photo meaning light and synthesis means putting together. In other words, plants use light to synthesize glucose. Plants use glucose just as we do for nutrition.
How does the human body produces photosynthesis?
we can produce photosynthesis when we eat plants or animals that also eat plants......................... XD *_*
What substances must a green plant obtain from its environment to carry on photosynthesis?
water(from soil)
carbon di oxide(from air)
chlorophyll(contained in the leaf)
energy(from sunlight)
What cellular structure is responsible for converting energy stored in glucose into ATP?
The mitochondria is responsible for converting energy stored in glucose into ATP through a process called cellular respiration. This process involves breaking down glucose molecules and using the energy released to produce ATP molecules, which are the primary source of energy for cellular activities.
How does light dependent and light independent reaction work together?
The Light Reactions Provide Energy Carriers For The Dark Reactions.
How could bright sun light affect photosynthesis in a plant?
the limiting factor for the processes of photosynthesis is the amount of sunlight , carbon dioxide and oxygen-nap
Requirements of light independent reactions?
light and water.
energy from the sun (light) is absorbed by photosystems I and II and used to energize the electrons whose energy is later used to make the molecules that act as energy carriers ATP (adenosine triphosphate) and the electron carrier NADPH.
Water molecules (H20) are used in photosystem II (note that photosystem II comes first in the process then photosystem I because they were named according to the order by which they were discovered). Enzymes break down water into hydrogen ions (H+), electrons (that replace those that left photosystem II-chlorophyll and other light-absorbing molecules- when energy from sunlight was absorbed), and oxygen molecules (which are given off as a waste product).
Where do you find chlorophyll?
Amazon.com is a great website that will provide online pictures, retailer information and pricing for any type of furniture you might be looking for including compact computer desks. They're also very affordable and have a nice variety.
Name two stages of photosynthesis?
There is the light-dependent stage, where sunlight interacts with choloropyll to set up an electron-transport chain, then there is the chemical stage, where glucose molecules are synthesized from CO2 and H2O.
How does cell respiration take place in bacteria?
In bacteria, cellular respiration occurs in the cytoplasm.
Does cellular respiration generally require oxygen?
Yes,it generally require.Organisms generally respire aerobically
Where is Calvin cycle occurring?
The Calvin cycle occurs in the stroma of the chloroplasts in plant cells. It is the second stage of photosynthesis, where carbon dioxide is converted into sugars using ATP and NADPH produced during the light-dependent reactions.
