The four substances recycled during photosynthesis and respiration are carbon dioxide, water, oxygen and glucose.

The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere. Energy from the sun enters a plant and is converted into glucose during photosynthesis.

Photosynthesis converts carbon dioxide and water into oxygen and glucose. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

Cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.

IN RESPIRATION THE RAW MATERIALS ARE OXYGEN AND GLUCOSE, WHICH ARE THE PRODUCTS OF PHOTOSYNTHESIS.

Lactic acid is mainly produced in muscle cells and red blood cells. It forms when the body breaks down carbohydrates to use for energy when oxygen levels are low.

We will discuss this in depth during aerobic respiration. The second step in anaerobic respiration is called fermentation. Fermentation starts with pyruvate (the end product of glycolysis). Depending on the organism, pyruvate can either be fermented into ethanol (a fancy name for alcohol) or lactate (lactic acid).

When the body has plenty of oxygen, pyruvate is shuttled to an aerobic pathway to be further broken down for more energy. But when oxygen is limited, the body temporarily converts pyruvate into a substance called lactate, which allows glucose breakdown—and thus energy production—to continue.

The extra oxygen you breathe in reacts with the lactic acid in your muscles, breaking it down to make carbon dioxide and water. As the lactic acid breaks down the cramps will begin to disappear. Lactic acid is also made in the mouth, where specialised bacteria convert glucose and other sugars to lactic acid.

Cellular respiration always begins with glycolysis, which can occur either in the absence or presence of oxygen. Cellular respiration that proceeds in the absence of oxygen is anaerobic respiration. Cellular respiration that proceeds in the presence of oxygen is aerobic respiration.

Answer Expert Verified. Photosynthesis – The process by which green plants prepare their own food in the presence of sunlight with the help of chlorophyll is known as photosynthesis. Respiration – The taking in of oxygen by us and exhaling out of the carbon dioxide is known as respiration. 3)Glucose.

Cellular respiration is the process by which organic sugars are broken down to produce energy. It plays a vital rolein the carbon cycle because it releasescarbon dioxide into the atmosphere. This means that cellular respirationcan be thought of as the opposite ofcarbon fixation in the carbon cycle.

Cellular respiration is the process by which cells in plants and animals break down sugar and turn it into energy, which is then used to perform work at the cellular level. The purpose of cellular respiration is simple: it provides cells with the energy they need to function.

During cellular respiration, glucose combines with oxygen to form carbon dioxide, water, and ATP. What happens to the energy in the bonds in glucose? The energy is transferred to oxygen. The energy is transferred to carbon dioxide.

What do cellular respiration and fermentation have in common? They both occur in the mitochondria, they both Harvest energy from sugars, they both require oxygen to occur, they both end up with pyruvic acid.

Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. In cellular respiration, glucose and oxygen react to form ATP.

Answer: At glycolysis stage, the net ATP production is 2 ATP.

The Krebs cycle takes place inside the mitochondria. The Krebs cycle produces the CO2 that you breath out. This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle). The net energy gain in fermentation is 2 ATP molecules/glucose molecule.

The energy to split glucose is provided by two molecules of ATP. As a result, there is a net gain of two ATP molecules during glycolysis. During this stage, high-energy electrons are also transferred to molecules of NAD+ to produce two molecules of NADH, another energy-carrying molecule..

net yield of 34 ATP per glucose molecule.

Cellular respiration is this process in which oxygen and glucose are used to create ATP, carbon dioxide, and water. ATP, carbon dioxide, and water are all products of this process because they are what is created.

– One should remember that one NADH is equal to 3 ATP. – In the beginning of glycolysis at the time of phosphorylation steps 2 ATP are consumed. ( Q ) After conversion of glucose molecules to pyruvic acid they in turn convert to Acetyl CoA….

Enzymes of Krebs cycle	No of energy molecules	No of ATP
Total	–	24 ATP

Respiration is a series of exothermic reactions that occur in the mitochondria of living cells in order to release energy from food molecules. This energy can then be used to produce heat, for movement, growth, reproduction and active uptake.

Complete answer: In prokaryotes, there are no mitochondria, the whole process of respiration occurs within the cytoplasm so no ATP is consumed in transporting across the organelle. Therefore, 38 ATPs are made from one glucose in bacteria while 36 are made in a eukaryotic cell.

ATP is generated in the plasma membrane of prokaryotic cells. ATP is the main energy storage molecule found in cells.
