6,415 Questions

When does photosynthesis mostly occur?

It depends on where you live. In temperate zones where all four seasons are clearly defined, photosynthesis occurs most during the spring and summer. In subtropical or tropical zones, photosynthesis occurs all year round.

What else does photosynthesis continually supply besides the main food?

In addition to food (glucose), photosynthesis continually supplies oxygen as a byproduct. This process helps to maintain the balance of oxygen and carbon dioxide in the atmosphere, which is essential for the survival of many organisms.

What is the coenjyme of transketolase?

The coenzyme of transketolase is thiamine pyrophosphate (TPP). It plays a crucial role in the transfer of two-carbon units in the pentose phosphate pathway.

What is the correct balanced formula of photosynthesis?

Aerobic respiration: In your tissues energy is needed for growth, repair, movement, excretion and so on. This energy is obtained from glucose supplied to the tissues by your blood. Aerobic respiration also requires Oxygen. The products of tissue respiration are Carbon Dioxide and water. Glucose + Oxygen = Carbon Dioxide + Water + EnergyC6H12O6 + 6O2 = 6CO2 + 6H2O +Energy The first one is a word equation. All it says is glucose and Oxygen are turned into Carbon Dioxide and water releasing energy. If you still don't understand this, just pretend that you are a parrot and memorise it. The second one is a balanced chemical equation. C6H12O6 ...means one molecule of glucose, but we are much too lazy to put a figure 1 in front of the glucose molecule. The C6 .means that the glucose molecule contains 6 atoms of Carbon. The H12 .means that the glucose molecule contains 12 atoms of Hydrogen. The O6 .means that the glucose molecule contains 6 atoms of Oxygen. 6O2 ...means 6 molecules of Oxygen, and each molecule contains 2 atoms of Oxygen. The left-hand side of the equation shows 6 atoms of Carbon, 12 atoms of Hydrogen and a total of 18 atoms of Oxygen. So does the right-hand side. The two sides of the equation must balance. 6CO2 ...means 6 molecules of Carbon Dioxide. The 6 multiplies the Carbon and the Oxygen. The C ...means one atom of Carbon, but again we are ever so lazy and do not bother to put a little figure 1 after the Carbon atom. So all together there are 6 atoms of Carbon. ( 6 times 1). The same number of Carbon atoms on each side. The O2 ...means that every molecule of Carbon Dioxide contains 2 atoms of Oxygen. So all together there are 12 atoms of Oxygen. Plus the 6 atoms of Oxygen in the water makes a total of 18. Same on both sides again. By now you should realise that there are six molecules of water and that each contains two atoms of Hydrogen and one atom of Oxygen. Now calculate the number of Hydrogen atoms on the right-hand side. You should find that 6 times 2 makes 12. So the Hydrogen atoms balance up as well. Photosynthesis: Carbon Dioxide + Water = Glucose + Oxygen 6CO2 + 6H2O + Light energy =C6H12O6 + 6O2 Here are the equations for photosynthesis. If you have understood the aerobic respiration equations Anaerobic respiration: Glucose = Ethanol + Carbon Dioxide + Energy C6H12O6 =2C2H5OH + 2CO2+Energy This is what yeast does when it runs out of Oxygen. It does not release so much energy and the ethanol (alcohol) is poisonous, so yeast will respire aerobically if it can. This is just a last resort. When we respire anaerobically we produce lactic acid instead of ethanol. It is the lactic acid which gives us cramp. So lactic acid is also poisonous and we must try to avoid making too much.

What reactants are used during photosynthesis?

Reactants used during photosynthesis are H2O (water) and CO2 (carbon dioxide) with sunlight energy.

Which light has the least affect on photosynthesis?

Green light has the least effect on photosynthesis because it is poorly absorbed by chlorophyll, which is the pigment responsible for capturing light energy during photosynthesis. This means that plants do not use green light as efficiently as other colors for photosynthesis.

What is a Smittybilt product best used for?

A product made by the company Smittybilt, would be used on a vehicle. According to the official website, Smittybilt manufactures and sells accessories, spare parts and general equipment for cars, jeeps and more. The products they offer are too many and varied to list them all, but a selection are: Cages, wrenches, side bars, bumpers, jeep tops, seat covers and more.

Why are ptoducts of photosynthesis important for the livelihood of man?

Products of photosynthesis, such as oxygen and glucose, are crucial for human survival. Oxygen is essential for respiration, while glucose provides energy for various metabolic processes in our bodies. Without these products, humans would not be able to survive.

What was earth's atmosphere like before photosynthesis?

Before photosynthesis, Earth's atmosphere was primarily composed of carbon dioxide, methane, ammonia, and water vapor. There was very little oxygen present. The emergence of photosynthetic organisms over billions of years dramatically altered the composition of the atmosphere to include more oxygen and less carbon dioxide.

What would happen if a plant has a mutation and did not produce pigment?

If a plant could not produce pigment then it would not be able to carry out photosynthesis. The photosynthetic pigment in the plant captures the light energy from the sun and is able to convert it to chemical energy. On the microscopic level, electrons are excited due to the energy of the photons and they reach a high energy state. Once these electrons fall back to ground state they release energy. The energy is focused on chlorophyll "a" which has the ability to lose electrons due to its structure. The lost electrons move through a transport chain and end up reducing NADP+ and indirectly help produce ATP which are needed in the Calvin cycle to help produce glucose. So without pigments, nothing would be able to capture the light energy and initiate photosynthesis.

How are pigments involved in the photosynthesis process?

The pigments are responsible for capturing the light energy from the sun and converting it to chemical energy. This is the first step of photosynthesis, so the pigments are responsible for initiating photosynthesis.

Is photosynthesis carried out by consumers?

No, photosynthesis is not carried out by consumers. It is a process that primarily occurs in autotrophic organisms such as plants, algae, and some bacteria. Consumers, like animals, obtain their energy by consuming other organisms.

Which process in plant cells uses chlorophyll?

Photosynthesis

Water, Sunlight, and Carbon Dioxide go into the chloroplast, and glucose and oxygen come out.

How can cell store the sugar that is produced in photosynthesis?

Cells can store the sugar produced in photosynthesis by ATP

1) be broken down by the mitochondria to supply energy to the cell.

2) be linked together in long chains to form cellulose and build the plant cell wall.

3) be moved to another part of the plant for energy, or moved to the root system for storage (in the form of starch).

What major type of organism can carry out photosynthesis?

Plants are the major type of organism that can carry out photosynthesis. They contain chlorophyll, a green pigment that helps convert sunlight into energy through the process of photosynthesis.

How does the chemical equation for cellular respiration relate to that of photosynthesis?

The chemical equation for cellular respiration is the reverse of the equation for photosynthesis. In cellular respiration, glucose and oxygen are used to produce carbon dioxide, water, and energy in the form of ATP. In photosynthesis, carbon dioxide and water are used with sunlight to produce glucose and oxygen. The two processes are interconnected as they represent opposite reactions in the cycle of energy conversion in living organisms.

What characteristic do photosynthesis and combustion share?

Photosynthesis and combustion both involve the conversion of chemical energy into another form of energy. However, in photosynthesis, light energy is converted into chemical energy, while in combustion, chemical energy is converted into heat and light energy through a chemical reaction.

What are the products of the light dependent reactions which required by the Calvin cycle during respiration?

The products of the light-dependent reactions (photosynthesis) required by the Calvin cycle during respiration are ATP and NADPH. These molecules provide the energy and reducing power needed for the Calvin cycle to convert carbon dioxide into glucose and other organic molecules.

Where does oxygen gas come from in photosynthesis?

The splitting of water by the process of photolysis in photosystem II. There the electrons and protons are used in the process of photosynthesis but oxygen gas is a byproduct that diffuses out of the stomata into the atmosphere.

What do plants tilt their leaves upwards during noon time?

To get more sunlight for a higher rate of photosynthesis

What 2 products can be extracted from seeds?

Oil and protein are two common products that can be extracted from seeds. Oil from seeds is often used for cooking, skincare, or biofuels, while protein can be used in food products, animal feed, or nutritional supplements.

Does red light promotes fern spore germination?

No, red light does not promote fern spore germination. Fern spores typically require moisture, suitable temperature, and suitable substrate for germination to occur. Light quality may have some effect on the process, but it is not a primary factor.

Can artificial light also be used by plants in photosynthesis?

Yes, artificial light can be used by plants in photosynthesis as long as it provides the necessary wavelengths (blue and red light) for the process to occur. However, natural sunlight is typically more effective as it contains a broader spectrum of light that is beneficial for plant growth.
