How is oxygen involved in the process of aerobic respiration?

There are two major processes in which glucose is broken down in cellular respiration: glycolysis and aerobic respiration. In the processes, the glucose is essentially broken down in order to create both water and carbon dioxide, out of the consumption of the glucose itself.

Aerobic respiration is the release of energy from glucose or another organic substrate in the presence of Oxygen. This means getting energy out of sugar (glucose).

Cellular respiration helps the plant with photosynthesis

In eukaryotes, the process of aerobic respiration occurs within these organelles.

Only plants can photosynthesize, but both plants and animals depend on respiration to release the chemical potential energy originally captured through photosynthesis.

The figure illustrates how closely photosynthesis and respiration are linked. As you can see, thanks to these two life-sustaining processes, plants and animals depend on each other to survive.

What is the purpose of fermentation, and under what environmental condition does it occur?

In bacteria, fungi, and some animal cells:

In lactic acid fermentation, the electron and H+ on NADH is transferred directly to the C3 pyruvates. This converts them into lactate. Typically, this type of respiration in animals can only occur for short periods because the energetic demands for ATP will eventually exceed the rate of production from glycolysis, alone. At this point, oxygen concentrations must rise again so that the lactate can be converted back to pyruvate and metabolized by aerobic respiration.

No new energy is released from these reactions, so the energy produced by anaerobic respiration is just what is produced in glycolysis - fermentation is just a mechanism for the cell to recycle the NAD to keep glycolysis going.

Now, we will examine the energy harvesting reactions that ALL living cells perform: Cellular Respiration.

Big Ideas Cellular Respiration and Photosynthesis

Photosynthesis is the first stage of energy flow through an ecosystem. You and all other animals on earth rely on the energy that plants store for life. But animals aren’t the only organisms that burn energy. Plants burn energy as they grow, too. In both plants and animals, the process of — which releases stored energy for use — occurs in the mitochondria inside each cell.

And where does cellular respiration happen

The major factors that affect the photosynthesis process are the sunlight (it needs to be there), the temperature (not too hot and not too cold, or else it will not work, since the plants can slow down at extreme temperatures), the existence of water (this is why you need to water your plants) and finally the existence of carbon dioxide, which pretty much does exist everywhere.

What Are Photosynthesis and Respiration? - dummies

Respiration consists of a complicated series of chemical reactions. In the first stage, glucose is oxidized, and the chemical potential energy of its bonds is transferred to the chemical potential bonds of an ATP molecule. The ATP molecule can then be transported throughout the cell where its stored energy is used to complete various tasks within the cell. This process releases carbon dioxide gas and water.

What Are Photosynthesis and Respiration

Photosynthesis is a chemical process, one that plants do and that we, as human beings, just find amazing. The process occurs whenever there is sunlight present, and with little more than the stores of energy that the plants create, they are able to create their own food and feed themselves. This is how they manage to survive even without moving.

Photosynthesis and Cellular Respiration, biology homework help

Aerobic respiration takes place in almost all living things. It is easy to get rid of the Carbon Dioxide and excess water; this is excretion (the removal of the toxic waste products of metabolism), and maximum energy is released from the glucose.

Respiration occurs in your cells and is fueled by the oxygen you inhale. The carbon dioxide gas you exhale is the result of a completed cycle of cellular respiration.
