Are mitochondria parasites or symbionts?

[rupol2000]

It is believed that these are symbionts that were originally bacterial parasites of eukaryotes, but then began to benefit in the form of increased production of ATP. In practice, increased ATP production is not confirmed, because when a person starts breathing during intense exercise, he experiences a breakdown. For example, at a distance of 400 meters, the last 100 meters are the most difficult, when it is no longer possible to maintain an anaerobic cycle and the sprinter begins to breathe. Further even worse.
Symbiosis is also not confirmed in practice. In fact, mitochondria hide from the attack of the immune system in cells, but as soon as they enter the bloodstream, they cause an immune response.

The behavior of mitochondria is no different from other cellular parasites such as the malarial bacterium. Could the malarial bacterium also be a symbiont instead?

Parasites don’t provide a benefit to the host; mitochondria do. 400m is much too short a distance for aerobic metabolism to kick in. That can often take a couple of miles, as I learned early in my cross-country days.

Why do you think so?

Absolute nonsense. The aerobic metabolism works whenever it respiration works.

You lost me with your "bacterial parasites of eukaryotes, but then began to benefit in the form of increased production of ATP. In practice, increased ATP production is not confirmed."

Bacterial parasites can cause severe illness and even kill you, so you'll have to get past the eww. It sounds like you're just skipping and assuming your conclusion.

 

[konradv]

Why do you think so?

They provide a service to the organism, ATP production, therefore by definition they aren’t parasites.

Absolute nonsense. The aerobic metabolism works whenever it respiration works.

Don’t know much about metabolism, do you? You gave it away by using the word ‘absolute’. Anyone familiar with the topic knows what I’m talking about. Anaerobic metabolism kicks in first and then the aerobic system ramps up, simple HS biology. Perhaps a review is in order.

He’s wrong about the parasite part; they’re symbionts.

They make ATP for themselves, it's just that there's a mechanism to extract it from inside the mitochondria. I think that from any bacterium the cell can also pull it out.

when breathing is working, there is always an aerobic

You’re a waste of time, if you refuse to at least check your facts. After 35 years of medical research, I can safely say you haven’t got a clue.

Just back off you fool. This is reliable data from biochemistry textbooks.

Solute transport across the impermeable mitochondrial inner membrane is essential for the function and survival of eukaryotic cells. The majority of these transport steps are catalyzed by membrane proteins of the mitochondrial carrier family (Monné and Palmieri, 2014). The archetypal member of the family, the ADP/ATP carrier, performs the vital role of transporting ADP into the mitochondrial matrix and ATP out of the mitochondrion to maintain high cytosolic ATP concentrations for energy-requiring reactions (Kunji et al., 2016). Every day, this carrier transports our own body weight in ADP and ATP, recycling each ATP molecule more than a thousand times. The carrier cycles between the cytoplasmic-open state (c-state), which can be trapped by the membrane-impermeable toxic inhibitor carboxyatractyloside (CATR)

The Molecular Mechanism of Transport by the Mitochondrial ADP/ATP Carrier

Mitochondrial ADP/ATP carriers transport ADP into the mitochondrial matrix for ATP synthesis, and ATP out to fuel the cell, by cycling between cytoplasmic-open and matrix-open states. The structure of the cytoplasmic-open state is known, but it has proved ...

What the hell did you think, it's doing charity work? It has own interests: to eat and breed.

 

[rupol2000]

But I don't believe in it at all. If mitochondria provided maximum energy, then intense and power loads would be aerobic, and would directly depend on respiration. But in fact, the opposite is true.

You don’t know anything. You’re just another one of those purveyors of fake news.

Read up on symbiosis. Your education is clearly lacking.

Intelligent Self-Design

Primitive life forms used their intelligence to select between (the root meaning of intellect) outside organisms and capture those that their intuition (root meaning: "on watch for or (negatively) guard against") told them were useful. We have captured many beneficial bacteria.
