Cellular respiration is the process by which organisms use oxygen to break down molecules to receive chemical energy for cell functions and takes place in the cells of animals, plants, and fungi, and also in algae and other protists however what is being discussed more specifically is aerobic respiration, a catabolic molecule that consume oxygen and organic molecules, producing adenosine triphosphate. The term cellular respiration includes both aerobic and anaerobic respiration but however is commonly used as a synonym to aerobic respiration. Cellular respiration occurs in the mitochondria of most cells and is an important process of life itself. In an abridged explanation, cellular respiration converts organic molecules, and oxygen into energy, water and carbon dioxide. Photosynthesis is the conversion of light energy to chemical energy that is stored in sugers or other organic compounds that occurs in plants, algae, and certain prokaryotes. (Campbell, 2008) Photosynthesis is a similar but drastically different process to cellular respiration, rather being the equivalent aerobic respiration in reverse. (Campbell, 2008) The main difference is that in photosynthesis, glucose is created from the conversion of light, while during respiration, glucose is created from the conversion of oxygen, or oxidation.

The highlight of this is chemiosmosis, a energy-coupling mechanism that uses energy stored in the form of a hydrogen ion gradient across membrane to drive cellular work. This is more commonly referred to as the electron transport train, pumping hydrogen protons across a membrane from a region of low hydrogen concentration to an area of high hydrogen concentration.The protons then

Transitioning between photosynthesis and respiration : CO2 cuts into carbon and oxygen, some of the oxygen is then released and the carbon mixes with H20. If it was mad and balanced, the effect of carbon and water will also affect glucose. This is called photosynthesis. Plants take the water and CO2 in order to make food (glucose) which sets the oxygen free.

The ability to carry out metabolic processes, or the chemical activity that occurs in all living organisms, is essential to maintaining life. The total metabolism of an organism is made up of anabolic and catabolic pathways. Anabolic pathways expend energy to build important molecules. On the other hand, catabolic pathways release energy to break down important molecules. The energy found in in these pathways is from respiration.

What is the overall balanced chemical equation for the combustion of glucose in cellular respiration? C6H12O6+6O2→6CO2+6H2O+ATP / glucose + oxygen → carbon dioxide + water + energy How does ATP release stored energy? ATP (adenosine triphosphate) is a nucleotide that consists of an adenine base attached to a ribose sugar, which is attached to three phosphate groups. Energy is released when one of the three phosphate groups is removed by breaking a phosphoanhydride bond during hydrolysis.

Photosynthesis consists of two stages, the light reactions and the dark reactions. The light reactions convert light into energy (ATP and NADHP) Occurs in thylakoid stacks of grana Sunlight is converted into ATP (free energy containing molecule) and NADPH (high energy electron carrying molecule) Chlorophyll absorbs light energy and starts a chain of

The stomata are the most critical piece to this process, as this is where CO2 enters and can be stored, and where water and O2 exit. Cellular respiration also known as oxidative metabolism is important to convert biochemical energy from nutrients in the cells of living organisms to useful energy known as adenosine triphosphate (ATP). Without cellular respiration living organisms would not be able to sustain life. This process is done by cells exchanging gases within its surroundings to create adenosine triphosphate commonly known as ADT, which is used by the cells as a source of energy. This process is done through numerous reactions; an example is metabolic pathway.

Introduction: Photosynthesis is a process where plants and other organisms transform the radiant energy of sunlight into the chemical energy of high-energy compounds by converting carbon dioxide and water into the simple sugar glucose. However, this process is not as simple as it seems. Photosynthesis occurs in two stages. The first stage is light dependent reactions and the second stage is light independent reactions. Each plant also has its own way to go through photosynthesis which is what makes plants different from one another.

In cellular respiration, your body uses glucose and oxygen in a process to make energy. The glucose is split in the cytoplasm of your cell, then its atoms go through a complex process which turns them into ATP, a useable energy source for your body. ATP can either be used, or stored in lipids for long term use. Lipids are one of the most diverse macromolecules because of the many functions they can perform. They make up a cell membrane, so without them, there would be no humans, they also can be used as a long term energy storage in the form of fat.

The Effect of Sugar Concentration on CO2 Production by Cellular Respiration in Yeast Introduction In this lab, our main focus was to find how sugar concentration affect yeast respiration rates. This was to simulate the process of cellular respiration. Cellular respiration is the process that cells use to transfer energy from the organic molecules in food to ATP (Adenosine Tri-Phosphate). Glucose, CO2, and yeast (used as a catalyst in this experiment) are a few of the many vital components that contribute to cellular respiration.

Simply because, we would lose our plants and the oxygen it provides, as a result, we wouldn’t be able to breathe. Cellular respiration is what happens when cells are broken down to create energy. Cellular respiration is important because it provides energy for our organisms to help our body function. Without both photosynthesis and cellular respiration, we wouldn’t be here to this day.

Introduction: Photosynthesis is a process used by plants and specific types of bacteria in order to make their own food source from sunlight to chemical energy. It is mainly occurred within the leaves of the plant. The reaction requires light energy in order for it to be absorbed by chlorophyll. During the reaction carbon dioxide, water is converted into glucose and oxygen as shown below: Figure 1 (photosynthesis uses light energy to convert carbon dioxide into a carbohydrate) (The Chemical Equation of Photosynthesis. 2018, Accessed 16 March 2018) There are two types of photosynthetic processes; one includes oxygenic photosynthesis, which is most common and demonstrated through plants, algae and cyanobacteria while the other one is an-oxygenic photosynthesis.

Cellular Respiration One of the main essentials of life that all organisms need in order to function in our world is, energy. We receive that energy from the food that we eat. Cellular respiration is the most efficient way for a cell to receive the energy stored in food. In cellular respiration, a catabolic pathway, which breaks down the molecules into smaller units, in order to produce adenosine triphosphate, also known as, ATP. ATP, is used by cells in the act of regular cellular operations, it is a “high energy” molecule.

Introduction Photosynthesis is the process of converting energy from sunlight to chemical energy known as ATP which is necessary for all living organisms. The photosynthetic process uses raw materials such as water and carbon dioxide and releases oxygen and sugar as a byproduct (Mader, S. 2010). The chemical equation is:

Germinating peas and maize respire at faster rates than fresh and dried peas and maize at room temperature and 400C(graph no). This could be because pea seeds have two cotyledons as compared to the single one of maize so oxygen usage is also more. These results support my hypothesis stated earlier. Respiration is an enzymatic process where enzymes are required at every step in the breakdown of glucose. At 600C for both peas and maize the respiration rate went down as the enzymes denatured.

Ventilation of a person through various activities Camila Gonzalez. This lab was made with the aim of proof that making different activities can alternate the ventilation rate, also is to see the variation of work our respiration system makes. We can see the different things and situations that can affect the normal process of ventilation and respiration, like the weather and the clothes that were limitations for doing this experiment because first the weather was so hot, so the person get tired early and began to ventilate faster and second the clothes wasn't appropriate for making the activities, because they also make weight and makes that the person get more tired. We use more than one person to make a comparison of the ventilation
