Bacteria generate energy through a process called fermentation, which does not require mitochondria. In fermentation, bacteria break down sugars to produce energy in the form of ATP.

What are the human cells without mitochondria?

Red blood cells do not have mitochondria. They rely solely on anaerobic metabolism for energy production, as they do not need to consume oxygen or generate ATP like other cells in the body.

What bacteria can survive without the presence of oxygen?

Anaerobic bacteria are able to survive without the presence of oxygen. These bacteria obtain energy through fermentation or anaerobic respiration, which does not require oxygen. Examples of anaerobic bacteria include Clostridium botulinum and Bacteroides fragilis.

Does bacterial cells contain mitochondria?

Well, bacteria is made up of a cell, and there is mitochondria in a cell, so therefore there are mitochondria in bacteria. Wrong, bacteric cells do not have any mitochondria because bacteria are prokaryotic cells and mitochondria are only found in eukaryotic cells. Actually: Mitochondria are in both animal and plant cells. They contain a circular chromosome that contains DNA. They are where most of the ATP is made inside a eukaryotic cell. They likely evolved from once free-living bacteria. Prokaryotic cells are only domain Bacteria and domain Archaea, but they all evolved from a single cell that was bacteria, but have now separated cells.

How does the presence of nutrients in a laboratory setting affect the growth of E. coli bacteria?

In a laboratory setting, the presence of nutrients can significantly impact the growth of E. coli bacteria. Nutrients provide essential building blocks for the bacteria to reproduce and thrive. Without sufficient nutrients, the growth of E. coli bacteria may be limited or slowed down. Therefore, the availability of nutrients is crucial for the optimal growth and proliferation of E. coli bacteria in a laboratory environment.

In what ways do facultative anaerobic bacteria differ from the other two types of bacteria in terms of their oxygen requirements?

Facultative anaerobic bacteria can survive with or without oxygen, while obligate aerobes require oxygen to survive and obligate anaerobes cannot survive in the presence of oxygen.

What term describes bacteria that can survive without the presence of oxygen?

Anaerobic bacteria or facultative anaerobic bacteria.

What are the human cells without mitochondria?

What is anaerobic respiration in bacteria?

Anaerobic respiration a form of respiration using electron acceptors other than oxygen. Many anaerobic organisms can respire only using anaerobic compounds and will die in the presence of oxygen.

What would be the result if a plant cell had chloroplast but lacked mitochondria?

If a plant cell had chloroplasts but lacked mitochondria, it would not be able to perform cellular respiration to generate energy in the form of ATP. This could severely impact the cell's ability to function properly, as ATP is essential for many cellular processes. The presence of chloroplasts would allow the cell to still carry out photosynthesis to produce glucose, but without mitochondria, it would not be able to efficiently convert this glucose into ATP.

What bacteria can survive without the presence of oxygen?

Why do green algae could not survive without mitochondria?

Green algae, like all eukaryotic organisms, require mitochondria to generate energy through aerobic respiration. Mitochondria produce ATP, the cell's primary energy source, through the process of oxidative phosphorylation. Without mitochondria, green algae would not be able to produce enough ATP to sustain their cellular functions and would not survive.

What are you doing every time you breathe and what is happening at the cellular level?

The function of the lungs when breathing is to pull in the oxygen our mitochondria need to burn sugar and remove the CO2 our mitochondria generate after breaking the sugar down( sugar can't be burnt without oxygen and we can't get oxygen to all our cells without lungs).

Differences between anaerobic respiration and aerobic respiration?

Aerobic Respiration is a respiration of a bacteria with oxygen. Glucose + Oxygen --> Energy + Water + Carbon Dioxide Anaerobic Respiration is a respiration of a bacteria without the presence of oxygen.

Could an organism survive without its mitochondria if all the other organelles were present?

Primordial bacteria have no organelles. They represent the stage of evolution before organelles were acquired. Organelles (probably) began as infectious bacteria invading ameoba-like cells. If the host didn't kill them off and they didn't kill the host then the bacteria become a sort of parasitic organelle. These can be removed without too much harm to the host. In fact the host would probably benefit by their removal. If the parasitic bacteria them started to provide some service to the host cell then the host benefits from their presence. If the service they provide duplicates some basic process of the host then the host will 'forget' how to do the service itself and rely solely on its (now) symbiotic organelles. This is a very common facet of living things: if you don't use a certain ability then you lose it. Removal of the organelles at this stage would be fatal to the host.

How oxygen helps bacteria grow?

Oxygen acts as a final electron acceptor in the bacteria's energy-producing processes, such as respiration. This allows bacteria to generate more energy for growth and reproduction. Without oxygen, some bacteria may use alternative pathways or be unable to grow altogether.

Could the cells survive without its mitochondria if all the other organelles were present?

no, mitochondria convert the sugar, can give it(the cell) Nutrients (food) to mainly keep it fresh and alive. Without cells mitochondria can't do its job. Without mitochondria cells can't do their job either
