The flow of what particle across the thylakoid membrane powers the production of ATP?
Protons (H+) flow across the thylakoid membrane during photosynthesis, creating a proton gradient. This gradient is used by ATP synthase to generate ATP from ADP and inorganic phosphate.
What is the first molecule to provide electrons for photosynthesis?
The first molecule to provide electrons for photosynthesis is water. Water is split into oxygen, protons, and electrons during the light-dependent reactions of photosynthesis. These electrons are then used to drive the production of ATP and NADPH, which are needed for the Calvin cycle to convert carbon dioxide into glucose.
What are the functions of the different pigments in the leaf?
Chlorophyll is responsible for photosynthesis, converting light energy into chemical energy. Carotenoids protect chlorophyll from light damage and broaden the spectrum of light that can be captured. Anthocyanins act as antioxidants, protecting the leaf from stress and regulating the plant's response to environmental signals.
What do mammals produce that plants use?
Mammals produce carbon dioxide through respiration, which is used by plants during photosynthesis to produce oxygen and glucose. Additionally, mammals produce waste products such as urine and feces that can serve as organic nutrients for plants.
Does the plant type affect photosynthesis rate?
Yes, different plant types have different photosynthesis rates based on factors like leaf structure, chlorophyll content, and environmental adaptations. Crops and plants like corn and sugarcane tend to have higher photosynthesis rates compared to woody plants like trees.
What gas does grass give off during photosynthesis?
During photosynthesis, grass gives off oxygen gas (O2) as a byproduct. This oxygen is released into the atmosphere as a result of the plant using sunlight to convert carbon dioxide (CO2) and water (H2O) into glucose and oxygen.
Do all producers conduct photosynthesis?
Yes they do. Producers refer to plants, and all plants use photosynthesis.
-Actually the answer is no, some autotrophs (producers) obtain energy by chemosynthesis. These are found deep in water were no light reaches.
How are the two types of mesophyll found in a leaf specialized for photosynthesis?
The two types of photosynthetic mesophyll are --
(i) Palisade cells which are vertically elongated cylindrical cells and
(ii) Spongy mesophyll cells that are spherical green cells.
How is primary productivity limited by water?
Primary productivity can be limited by water availability in terrestrial ecosystems, as water is needed for photosynthesis to occur. In aquatic ecosystems, primary productivity can also be limited by water availability, as light penetration can be reduced in murky waters, limiting the amount of photosynthesis that can take place. Additionally, drought conditions can directly reduce primary productivity in both terrestrial and aquatic ecosystems.
Which substances must a green plant obtain from it's environment to carry on photosynthesis?
A green plant must obtain water, carbon dioxide, and light energy from its environment in order to carry on photosynthesis. Water is absorbed from the soil through the roots, while carbon dioxide is taken in from the surrounding air through small openings in the leaves called stomata. The light energy needed for photosynthesis is absorbed by chlorophyll in the plant's leaves from sunlight.
Why are cellular respiration and photosynthesis called mirror processes?
Because the reactants required for cellular respiration (glucose and oxygen) are the products ofphotosyntheses And the and the products of cellular respiration (carbon dioxide and water) are the reactants of photosynthesis.
Is glucose made during light-dependent or light-independent reactions?
Glucose is made during the light-independent reactions (Calvin cycle) of photosynthesis, where carbon dioxide is converted into glucose using ATP and NADPH produced during the light-dependent reactions.
What other sorts of stress cause p lunula cells to emit light?
Aside from mechanical stress, other types of stress that can cause piezoluminescence in p lunula cells include electrical stress, thermal stress, and chemical stress. These stressors can trigger the release of energy, resulting in light emission from the crystals in the p lunula cells.
What happens when a chloroplast doesn't do its job?
When a chloroplast doesn't do its job, the plant may not be able to photosynthesize properly, leading to a decrease in growth and overall health. This can result in the plant not producing enough food to sustain itself, ultimately impacting its ability to survive.
Name of Organisms that use photosynthesis to produce glucose?
An organism that uses Photosynthesis to produce glucose is called an Autotroph. Autotrophs are also called "self feeders" because they can produce food(glucose) for their own cells, such as plants. (A Heterotroph is an organism that consumes other organisms to get food for their cells, such as humans.)
What is released during photosynthesis when cells take in CO2?
Oxygen is released as a byproduct during photosynthesis when cells take in carbon dioxide. This oxygen is crucial for supporting respiration in living organisms.
What will be the result of photosystem you being exposed to less sunlight?
If photosystem II is exposed to less sunlight, there will be reduced production of ATP and NADPH through photosynthesis. This can lead to a decreased energy supply for the plant to carry out essential metabolic processes and growth.
Did Calvin Harris used to work in marks and spencers?
yes his did until a top produce discovered his talent and signed him up
The reaction in photosynthesis can be endergonic or exergonic?
Yes, the reaction in photosynthesis can be both endergonic and exergonic. The overall process of photosynthesis is endergonic, requiring energy input from sunlight. However, individual reactions within photosynthesis can be exergonic, releasing energy as they proceed.
How many ATP molecules can the cell produce from a single molecule of glucose through glyclosis?
The cell can produce a net of 2 ATP molecules from a single molecule of glucose through glycolysis. This process involves breaking down glucose into pyruvate and generating ATP through substrate-level phosphorylation. Additionally, glycolysis also produces NADH which can contribute to the production of more ATP in the electron transport chain.
A compound that is split during photosynthesis is?
Water is the compound that is split during photosynthesis, producing oxygen and hydrogen ions in the process. This splitting of water is a crucial step in the light-dependent reactions of photosynthesis that ultimately leads to the production of ATP and NADPH for use in the Calvin cycle.
What do light independant reactions produce?
The light-independent reactions of photosynthesis, also known as the Calvin cycle, produce glucose, the main source of energy for plants. This process utilizes ATP and NADPH generated during the light-dependent reactions to convert carbon dioxide into sugar molecules.
How do you perform exsanguination?
Exsanguination is a medical term that refers to the process of removing blood from a person or animal. This can be done through surgical procedures where blood is drained from vessels, such as during blood donation or in medical emergencies to control bleeding. It is important to perform exsanguination safely and under controlled conditions to prevent complications.
How do plants get the carbon dioxide they need during photosynthesis?
That's easy, if you're talking about from which part of the plant they inhale it with, that would be the leaf, or pine needle. If you're asking how, the leaf simply has hundreds of tiny, microscopic holes in which the plant itself uses to take in CO2. (Carbon Dioxide)
Can photosynthesis occur on Mars?
no because you need CO2
and you don't have that on mars
but you do have sunlight which is also needed
EDIT: Thursday September 27, 2012
Mars consists of 95.23% carbon dioxide (CO2).
The only limiting factors is UV protection like Earth's ozone layer and liquid water.
The answer is still NO, Not naturally. photosynthesis "may be" possible with man made habitats designed to protect from UV radiation.
Mars has an abundance of CO2!
