Photosynthesis and aerobic respiration

During the pay-off phase of glycolysis, four phosphate groups are transferred to ADP by substrate-level phosphorylation to make four ATP, and two NADH are produced when the pyruvate are oxidized. For this reason, they are now considered as part of the cyanobacterial group.

The Calvin Cycle produces one molecule of sugar for every six molecules of carbon dioxide.

Difference Between Aerobic & Anaerobic Cellular Respiration Photosynthesis

Therefore they use all the energy on jumping over the fences and then they have steady canter to gain the energy they have lost for the next fences. Carbon fixation[ edit ] Cyanobacteria use the energy of sunlight to drive photosynthesisa process where the energy of light is used to synthesize organic compounds from carbon dioxide.

The latter two — Nostocales and Stigonematales — are monophyletic, and make up the heterocystous cyanobacteria.

To break away from the parent colony, a hormogonium often must tear apart a weaker cell in a filament, called a necridium.

This video gives a more detailed discussion of the topic of cellular respiration. The waste products are either recycled when the organism re-enters an aerobic state or removed from the organism. Anaerobic respiration is some thing that is able to live in the absence of oxygen.

All You Need to Know About Photosynthesis and Cellular Respiration

The tiny marine cyanobacterium Prochlorococcus was discovered in and accounts for more than half of the photosynthesis of the open ocean. In this case, a photosynthesizing cyanobacteria that was engulfed in some ancient eukaryotic cell. During the light-independent reactions, the energy produced during the light reactions is used to produce sugar molecules from carbon dioxide through a process called the Calvin Cycle.

Substrate level phosphorylation which includes Glycolysis, and the Krebs cycle a. Continue reading for more information on photosynthesis and cellular respiration, with special emphasis on the relationship between the two.


Aerobic respiration is a process of cellular respiration that uses the oxygen in order to break down the molecules, which then release electrons and creating energy. The oxygen produced by plants during photosynthesis is what humans and animals inhale for the blood to transport to the cells for respiration.

It has been widely reported that cyanobacteria soil crusts help to stabilize soil to prevent erosion and retain water. In Pleurocapsales, the cells have the ability to form internal spores baeocytes.

This video gives a quick review of respiration and discusses a lab which tests how temperature can alter the rate of respiration in yeast. Examples of fermentation include lactic acid fermentation in humans and other animals and ethanol fermentation by yeast.

Examples of fermentation include lactic acid fermentation in humans and other animals and ethanol fermentation by yeast. These alternate acceptors include nitrate, sulfate, sulfur, carbon dioxide and other molecules.

Difference Between Aerobic & Anaerobic Cellular Respiration Photosynthesis

Photosynthesis is a process wherein synthesis of sugar glucose is carried out using sunlight which acts as the radiant energycarbon dioxide and water. Hope it gives you the basic idea of what is happening in each of above processes.

These were originally grouped together as the prochlorophytes or chloroxybacteria, but appear to have developed in several different lines of cyanobacteria. Biology textbooks often state that 38 ATP molecules can be made per oxidised glucose molecule during cellular respiration 2 from glycolysis, 2 from the Krebs cycle, and about 34 from the electron transport system.

Aerobic Respiration Aerobic respiration occurs in the presence of oxygen and yields the majority of energy for organisms capable of aerobic respiration. Four molecules of ATP per glucose are actually produced, however, two are consumed as part of the preparatory phase.

Despite the differences between these two processes, there are some similarities. What is the main difference between aerobic respiration and anaerobic respiration.

In the process of cellular respiration, the biochemical energy derived from nutrients is converted to adenosine triphosphate ATPwhich is necessary for these organisms to facilitate various life functions.

Despite the differences between these two processes, there are some similarities. Simply put, photosynthesis is a chemical process by which plants, algae as well as some species of bacteria produce their own food using sunlight, carbon dioxide and water.

These processes are important contributors to the cycling of nutrients within soils as well as allowing these organisms to colonize areas uninhabitable by other organisms. Hence in photosynthesis you have the light dependent reactions and the dark reactions while in respiration there is aerobic respiration and anaerobic respiration.

In photosynthesis light dependent reactions, ultra violet light strikes chlorophyll pigments which excites electrons leading to separation of oxygen molecules from carbon dioxide.

Photosynthesis Photosynthesis is the process by which organisms that contain the pigment chlorophyll convert light energy into chemical energy which can be stored in the molecular bonds of organic molecules (e.g., sugars).

Cyanobacteria / s aɪ ˌ æ n oʊ b æ k ˈ t ɪər i ə /, also known as Cyanophyta, are a phylum of bacteria that obtain their energy through photosynthesis, and are the only photosynthetic prokaryotes able to produce oxygen. The relationship between photosynthesis and cellular respiration is such that the products of one system are the reactants of the other.

Photosynthesis involves the use of energy from sunlight, water and carbon dioxide to produce glucose and oxygen. Photosynthesis and cellular respiration are the life processes performed by most living organisms to obtain usable energy from nature.

Cellular respiration

While photosynthesis is performed by most plants which can prepare their own food, most animals fulfill their energy requirements through cellular respiration.

If photosynthesis and/or aerobic respiration were present in the ancestor of Cyanobacteria, it is expected that genes for complex III would be congruent within the Cyanobacteria phylum.

However, if photosynthesis is a derived feature of Oxyphotobacteria, and aerobic respiration evolved after the rise of oxygen, then the Cyanobacteria classes.
