Mitochondria are membrane-bound organelles found in most eukaryotic cells, and they are often referred to as the ‘powerhouses of the cell’ because they generate adenosine triphosphate (ATP), the cell’s primary energy currency, through a process called oxidative phosphorylation. They have a double-membrane structure, with the inner membrane folded into cristae to increase surface area for energy production. Mitochondria contain their own circular DNA, which is separate from the nuclear DNA, and this allows them to produce some of their own proteins. They are believed to have originated from a symbiotic relationship between ancient eukaryotic cells and free-living prokaryotes, a theory known as the endosymbiotic theory. In addition to energy production, mitochondria play roles in cell signaling, apoptosis (programmed cell death), and calcium homeostasis.
I’m not sure how you think critical thinking works. Do you have some sort of magical logic flow that doesn’t requiere some base understanding of facts?
Guy trying to sell quartz as “energy enhancing crystals” -> no understanding as to how body energy works -> might be legit, let’s give it a try
Guy trying to sell quartz as “energy enhancing crystals” -> knowing that available body energy is dictated by ATP and has nothing to do with crystals -> this smells like a scam
Critical thinking is about being able to apply knowledge of what you know to what you are currently being told. You need some basis of real, provable facts for it, which is why if you had a bio course, you also likely had some lab component to it as well.
Sure, I hear you cry, but all of that information isn’t something I need to know basically ever! Well, you’re correct, but a fun thing about learning is that the deeper you cut into a subject, the more you remember. You probably wouldn’t remember much if the entire unit only said “mitochondria is the powerhouse of the cell”.
And doing these deep cuts to reinforce the basics of understanding work. There is a reason that “mitochondria is the powerhouse of the cell” is a meme, and it’s because everyone remembers that part, not nessessarily the part that they have their DNA that is always inherented from your mother and is referred to as mDNA.
I hope this helps you to think critically against the continued push against critical thinking, particularly to the claim that what you learned in school has nothing to do with doing it.
The mitoncondria meme is a byword for useless knowledge.
Learning a series of science trivia will simply not teach you the structure of critical thinking.
Reciting a series of science fact is not a critical thinking activity, it is rote memorization of trivia.
Yes, effective critical thinking relies on a wealth of knowledge, but critical thinking is a set of applied skills about finding “your truth”. These skills simply cannot be acquired by downloading a series of establishmebt vetted facts.
If anything, critical thinking would be better learned by teaching flat earth theory, without any disclaimer. You needs exposure to real false information at a minimum.
You need to learn healthy distrust of authorities. Something I have not encoutered once in 15 years of dreadful, boring and painful schooling.
I see what you’re getting at, and you’re not wrong to think about how the lessons we teach kids from the minds and skills we want them to have. There’s positives and negatives to the liberal arts education, and it could be said that it is just as much of what is left out then what is kept in. The choice to teach about mitochondria and not the Krebs Cycle is odd from a scientific perspective, but if you know about endosymbiosis then it’s a lot harder to accept that all organisms appeared independently a few millennia ago. But once you view a liberal arts education from this perspective then you see these biases everywhere. For example, how many world history classes talk about the Tamil Kings, or the Warring States period of China? It’s a lot easier to other a region you don’t know the history of.
So we have to ask, what purpose should education serve? What knowledge and skills should we expect people to have by the time they reach adulthood? Add what is the best way to disseminate those?
The stated goal of high school level education is to create well roubded individuals. But individuals that know about mitochondria but not how fucked up the tax code is and how to survive all the finance predators? That know about Christopher Columbus but not how to change the tires on their cars ? That is not a well rounded to me. You have to know how to live before learning about biology trivia.
Ah yes learning critical thinking
Here is a series of indisputable statements.
