Gasoline and oxygen combining to release energy and waste products including carbon monoxide is that physical or chemical?

That process is a chemical reaction, as the molecules of gasoline and oxygen are rearranged to form new substances (carbon monoxide, carbon dioxide, water vapor) with different properties than the original substances.

Photosynthesis by light energy is converted into what?

Photosynthesis involves the transformation of light energy into chemical energy.

What are the raw materials for indoxycarb?

Indoxycarb is synthesized from the raw materials acetanilide and 2,3-dihydro-2,2-dimethyl-7-benzofuranyl methoxyacetate. These raw materials undergo specific chemical reactions to produce the final compound indoxycarb.

Why do you need lighting on stage?

Lighting on stage is essential for creating ambiance, setting the mood, focusing the audience's attention on specific areas or actors, emphasizing emotions, and enhancing the overall visual experience of a performance. Different lighting designs can greatly impact the storytelling and effectiveness of a production.

What type of reaction occurs when chlorophyll breaks down into new substances?

The breakdown of chlorophyll involves a chemical reaction known as decomposition, where chlorophyll molecules are broken down into simpler substances. This process is catalyzed by enzymes and can result in the formation of new compounds such as phytol and phaeophytin.

Where does Rudy mostly take place at?

Rudy Ruettiger (spelling may be off) went to the University of Notre Dame in South Bend, IN. Most scenes in the movie are filmed on the Notre Dame campus or on the adjoining campus of Holy Cross Junior College.

In what sort of soil would liverworts and hornworts be expected to be found?

Liverworts and hornworts are typically found in damp, shady environments with nutrient-rich soils, such as in forests, along stream banks, or in wetlands. They prefer soils that are well-draining and provide the moisture needed for their survival.

Where is most energy released during photosynthesis?

Most of the energy is released during the light-dependent reactions of photosynthesis, specifically in the chloroplasts' thylakoid membranes where light energy is used to convert water and sunlight into ATP and NADPH. These high-energy molecules then fuel the Calvin cycle, where glucose is ultimately produced.

What organelle converts glucose to energy by the process of cellular respiration?

Mitochondria are specialized organelles that produce energy for the rest of the cell by using glucose. You can think of it as the powerhouse of the cell.

What do you hope to satisfy by using raw materials?

By using raw materials, I hope to satisfy the need for creating products that are authentic, sustainable, and environmentally friendly. Raw materials provide the foundation for innovative and unique designs, allowing me to create something meaningful and lasting.

What are the major components needed for the production of oxygen-carbon dioxide?

The major components needed for the production of oxygen and carbon dioxide are sunlight, water, and plants. Through the process of photosynthesis, plants use sunlight to convert water and carbon dioxide into oxygen and glucose. This process is essential for the survival of most living organisms on Earth.

Why is photosynthesis an important process in ecosystems?

Photosynthesis is the way plants produce their food. They take water, sunlight, soil nutrients, etc, and turn it into a sugar which they can digest. Without the process of photosynthesis plants would not be able to eat and would die. Leaving people and animals who would normally eat a certain plant to starve.

--------------------------------------------------------------------------------------------------------------

Photosynthesis is the process by which plants trap the Sun's energy to make their food. It is therefore the process that supports ALL the life in an ecosystem.

What percentage of the world's photosynthesis is due to algae?

Percentage wise I am unsure but I do know that Phytoplankton (tiny plants living in the oceans) are alone responsible for around 50% of the oxygen in our atmoshere. That is an astronomical amount considering they are so widely consumed. Hopefully somebody will be able to elaborate on my answer but it should give you a better idea of how much photosynthesis occurs in the sea.

Is it true that some of the glucose required for cellular respiration in humans is obtained by eating glucose?

Human cells obtain energy by a process called respiration. This process is carried out in organelles in the cell called the Mitochondria. A Mitochondrion uses Glucose and Oxygen this reaction to form its two waste products, carbon dioxide and water, with the useful by product of energy, in the form of something called 'ATP'. Unless you are above the age of sixteenish, you will not need to know what ATP is, or even that it exists.

The word equation for respiration is:

Glucose + Oxygen → Carbon Dioxide + Water (+ Energy)

The last part in brackets is sometimes excluded.

The symbol equation is:

C6H12O6 + 6 O2 → 6 CO2 + 6 H2O

Due to the fact that energy has no chemical value, it is excluded from this equation universally.

This explanation is rather long, and I wrote it for intention of the asker reading it and taking interest. Of course, in the unfortunate circumstance in which you could not care less about all the time I have taken to answer this question in detail for you, the simple and boring one sentence answer is:

Human cells obtain energy via the process of Respiration (which takes place in the Mitochondria of the Cells). Depending on your year/grade, you may want to exclude/include the last part.

Good Luck!

Do plants inhale oxygen in respiration?

"Plants" do not possess a diaphragm and thus lack the ability to "inhale", rather they use pores on the surface of the leaf called Stomates. Being able to open and close according to external conditions, Stomates allow plants to exchange airborne gases and play a crucial role in respiration.

Can you reverse photosynthesis and get respiration in cells?

Respiration and photosynthesis are two seoarate processes, so reversing photosynthesis would not give you respiration.

However the two processes are in some ways the reverse of each other. Photosynthesis uses CO2 and produces O2. Respiration uses O2 and produces CO2.

What happens to the oxygen produced by plants during photosynthesis when the plant lives in water?

The oxygen produced by plants during photosynthesis in water is released into the surrounding water. It can dissolve in the water and be used by aquatic organisms for respiration or released into the atmosphere if the water is disturbed.

What is the gas that is taken from the air and converted to glucose in photosynthesis?

The gas that is taken from the air and converted to glucose in photosynthesis is carbon dioxide (CO2). Through the process of photosynthesis, plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Describe the path taken by water at the moment it enters the leaf and leaves through the stomata?

Water enters the leaf through the roots and moves up through the stem to the leaves via the xylem vessels. Once in the leaf, water moves through the mesophyll cells and eventually evaporates from the stomata as water vapor during transpiration.

Why zero order reaction depends upon light?

A zero-order reaction is independent of the concentration of reactants and proceeds at a constant rate. Light can influence the rate of a zero-order reaction by providing the activation energy needed for the reaction to occur. In some cases, light can also act as a catalyst, speeding up the reaction without being consumed itself.

Thylakoid membranes bring together the components necessary to carry out the?

Thylakoid membranes bring together the components necessary to carry out the light-dependent reactions of photosynthesis, including pigments like chlorophyll, electron transport chain proteins, and ATP synthase. These components are involved in capturing light energy, converting it to chemical energy in the form of ATP and NADPH, and producing oxygen as a byproduct.

Which option properly summarizes the inputs and outputs of the Calvin cycle?

1. 6 carbon dioxide molecules combine with six 5-carbon molecules forming twelve 3-carbon molecules.

2. The 12 3-carbon molecules are converted into high-energy forms.

3. 2 of the 12 3-carbon molecules are removed and the plant uses them to produce sugars, lipids, amino acids, and other compounds.

4. The 10 3-carbon molecules What_are_the_four_steps_in_the_Calvin_cycleback into six 5-carbon molecules, which combine with 6 more carbon dioxide molecules.

The process starts over.
