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.

What are the reactans of photosynthesis?

The formula of the whole process is: carbondioxide + water -----(light and chlorophyll)-----> oxygen + water + glucose so clearly, the solid reactants are carbon dioxide and water but you can also include sunlight.

What are some factors that affect photosynthesis?

Some factors that affect photosynthesis include light intensity, carbon dioxide levels, temperature, and water availability. Changes in any of these factors can impact the rate of photosynthesis in plants.

In what parts of plants does photosynthesis take place?

In the leaves of the plant. The leaves absorb energy from the sun light to make the energy needed for the plants to produce their food. For more information you can use a botany book. Botany is the study of plants. In the leaves of the plant. The leaves absorb energy from the sun light to make the energy needed for the plants to produce their food.

Could photosynthesis occur in a plant outside at night?

No, photosynthesis cannot occur at night because it requires sunlight to drive the process. Without light, the plant cannot convert carbon dioxide and water into glucose and oxygen. Photosynthesis only takes place during the day when sunlight is available.

What gets used up during respiration?

During respiration, oxygen is used up as it is required for the process of creating energy. Carbon dioxide is produced as a waste product and is expelled from the body through exhalation. Additionally, glucose is broken down to release energy during cellular respiration.

Importance of photosynthesis?

Photosynthesis is crucial for life on Earth as it is the process by which plants, algae, and some bacteria convert sunlight into chemical energy, producing oxygen as a byproduct. This process is the foundation of the food chain, providing energy for almost all living organisms. Additionally, photosynthesis helps regulate the Earth's atmosphere by removing carbon dioxide and releasing oxygen, contributing to a stable climate.

What organisms carry out photosynthesis?

Plants, algae, and some bacteria are the main organisms that carry out photosynthesis. They contain chlorophyll, a green pigment that absorbs sunlight and converts it into chemical energy through the process of photosynthesis.

What molecule is split during the light reactions of photosynthesis to release oxygen?

Water molecule is split during the light reactions of photosynthesis to release oxygen.

What are the products of the light reaction and how they formed?

The products of the light reaction are ATP, NADPH, and oxygen. These molecules are formed through the process of photophosphorylation in the thylakoid membrane of chloroplasts. Water is split into oxygen, protons, and electrons, providing the electrons needed to generate ATP and NADPH.

Does photosynthesis have Kreb's cycle in it?

No. Krebs cycle (also called the citric acid cycle or the tricarboxylic acid cycle) is responsible for the final breakdown of food molecules to form carbon dioxide, water, and energy within the cells of all animals and higher plants and in most bacteria.

Photosynthesis occurs in what organelles?

Photosynthesis occurs in the chloroplasts of plant cells. These organelles contain the pigment chlorophyll, which captures sunlight and converts it into energy through a series of chemical reactions. This process is essential for producing glucose, the energy source for the plant.

In what part of the plant does photosynthesis take place?

Photosynthesis primarily takes place in the leaves of plants. Specifically, it occurs in the chloroplasts, which contain the pigment chlorophyll that captures light energy for the photosynthetic process.

What is dark reaction process?

* the second phase of photosynthesis, that does not require the presence of light, during which ATP releases stored energy that is used to convert carbon dioxide molecules into sugars and other nutrients * The dark reactions of photosynthesis doesn't require the presence of light to photosynthesize. * The second stage of photosynthesis, not requiring light to occur, and during which energy released from ATP drives the production of organic molecules from carbon dioxide. * there are 2 main stages in potosyntesis. the light reaction occurs only in the presence of light while dark reaction happens both when there is light and when it is dark.

List the reatants and products of photosynthesis and respiration?

The overall reactants of photosynthesis are carbon dioxide and water.

The overall products of photosynthesis are glucose and oxygen.

The overall reactants of aerobic respiration are glucose and oxygen.

The overall products of aerobic respiration are carbon dioxide and water.

Green plants are important to animals because the plants?

Green plants are primary producers, many (primary consumers) feed off of them, this passes food energy up the food chain.

Grass grows, cows eat grass, cows produce milk and humans eat cows

What are causes of photosynthesis?

Photosynethesis means the process by which green plants convert carbon dioxide to sugar and oxygen using sunlight e.g. Photosynethesis is the process by which plants, some bacteria use the energy from sunlight to produce sugar, they do this for energy.

What are six minerals needed in photosynthesis?

The six minerals needed in photosynthesis are carbon, hydrogen, oxygen, nitrogen, potassium, and magnesium. These minerals play essential roles in various processes like the formation of glucose, synthesis of chlorophyll, and transportation of nutrients within the plant.

What compounds do plants use to make glucose molecules and where do they get it from?

Plants use carbon dioxide and water to make glucose molecules through the process of photosynthesis. Carbon dioxide is taken in from the atmosphere through tiny pores in the leaves called stomata, and water is absorbed from the soil through the plant's roots. These compounds are converted into glucose with the help of sunlight and chlorophyll.

Can a plant such as a mushroom manufacture glucose by the process of photosynthesis?

No, mushrooms cannot perform photosynthesis as they do not have chlorophyll, the pigment needed to convert sunlight into glucose. Instead, mushrooms obtain nutrients by breaking down organic matter through a process called decomposition.

How does photosynthesis help us survive?

Photosynthesis helps us survive because it is a way for plants, grass, and trees to produce it's own food so they won't die.Plants, trees, and grass produce oxygen and breath in the carbon dioxide so we can breath in fresh air and survive.

What is the source of the carbon and oxygen that are part of the glucose made during photosynthesis?

"the equation:6 CO2(gas) + 12 H2O(liquid) + photons and Chlorophyll → C6H12O6(aqueous) + 6 O2(gas) + 6 H2O (Water )

That means = For every single molecule of Glucose six molecules of CO2 and twlwve molecules of H2O are used up as raw material . Chlorophyll and chloroplasts are used as the machinery AND Light is the source of power or energy !!

Now let us turn to your question =

where does the Oxygen and Carbon come from?

Ans = The CO2 gas that enters the leaf through the stomata is the source of Carbon in Glucose .

It is linked with H2O to form glucose .

So finally Oxygen and Carbon in glucose come from two sources CO2 & H2O "

Where are enzymes associated with light dependent reactions of photosynthesis located?

Enzymes associated with the light-dependent reactions of photosynthesis are located in the thylakoid membranes of the chloroplasts. Key enzymes involved include ATP synthase, cytochrome b6f, and the enzyme complexes involved in the photosystems (PSII and PSI). These enzymes work together to capture light energy and convert it into chemical energy in the form of ATP and NADPH.
