Metabolism & Nutrition, Part 1: Crash Course A&P #36

Metabolism & Nutrition, Part 1: Crash Course A&P #36

Metabolism is a complex process that has a lot more going on than personal trainers and commercials might have you believe. Today we are exploring some of its key parts, including vital nutrients — such as water, vitamins, minerals, carbs, fats, and proteins — as well as how anabolic reactions build structures and require energy, while catabolic reactions tear things apart and release energy.

  1. Listen here crash course before you convince the world to stop eating meat…..acknowledge the only source of complete protein comes from animals!

  2. 6:00 – It’s not a marketing war. It’s simply if you eat fruits and veggies you will get enough fat. Possibly chuck in some nuts and seeds now and again. It’s not a war against fat, it’s a war against eating foods high in fat, because these foods cause more harm then good.

  3. But dr.sebi said glucose is the number 1 enemy in disease. To avoid glucose as much as possible. But that doesn’t make since if we need it to produce atp. How did Dr. Sebi go 2 months eating nothing but a plant? Makes no sense to me

  4. Vitamin K2, in addition to its expected role in blood clotting, helps the body transfer calcium out of arteries and into bones, thus protecting against both heart disease and osteoporosis.
    Oh, and neurons don’t run exclusively on glucose. They can derive up to 75% of their energy from ketone bodies if you’re on a low-carbohydrate diet.
    And plant protein sometimes has lousy bioavailability. The fact that grains have tons of amino acids in them doesn’t mean you can actually get at them.

  5. What is a low energy person? energy comes from food only. If you don’t eat 3 times a day, you suffer on long term; immune system weaker , bones weaker etc. donkeys in security have their own science

  6. I had to pause video like 10 times not because I’m slow but there are so much to learn and analize too much info at the time lol

  7. I just have to say thank you. And for all the people out there who complains about how fast he speeks. Dudes you can adjuste the velocity or watch another video. Search for solutions and don let hate on the comments section.

  8. Has anyone noticed the %s at the beginning add up to 101%? I literally did the maths twice, and then with a calculator because I thought I’d gone mad…

  9. The clipping together of his sentences so that there’s never a millisecond of silence between his points is incredibly fatiguing on the ear and the mind.

  10. You do NOT need glucose to produce ATP Hank. Ketones are more efficient.
    Please research the topic more thoroughly and update your beliefs.

  11. I love these vids but at around 5mins, ‘glucose is the be all that your body needs to drive atp’ no, ketones (catabolism of adipose tissue or body fat) also create atp and on far greater amounts and efficiency with less water and oxygen. No essential carbohydrates. The small amount of glucose needed by the body in some cells can be made by the liver from protein (glyconeogenesis).

  12. Hi HANK…. hee hee hee, I love your glassessssss *giggles* you make me feel special. My parents never look at me and tell me to look in the corner for 5 hours a day. Please come and visit me in Yorkshire! love you!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I want to give thos glassessssssss a good licking. 😛 Whats that on your desk :).
