What molecule Did Hank say was the star of the show of the global food chain?

The star of the show here is glucose, because it's truly fundamental, by which I mean, like, number one on the global food chain, because it comes from the sun. All biological energy is originally captured from the sun by plants as glucose through photosynthesis.Feb 13, 2012

Who does the biology crash course?

Hank GreenHank Green teaches a visually engaging crash course on biology with this series of high quality YouTube videos. Perfect for highschool students, or those without a strong background in biology.

What you eat belongs to biomolecules?

What makes food? All organic (naturally occurring) molecules are classified into 4 general categories: carbohydrate, lipid, protein, and nucleic acid. Foods you consume consist of these 4 molecules.

What happens to the biological macromolecules in the food we eat?

As food travels through your digestive system – in fact, from the moment it hits your saliva – it is being worked over by enzymes like these. The enzymes break down large biological molecules, releasing the smaller building blocks that can be readily absorbed and used by the body.

What is one thing that biological molecules do quizlet?

Single and double carbohydrates, monosaccharides and disaccharides, provide energy for living organisms, while larger carbohydrates, polysaccharides, store energy and are used as structural building-blocks in living things (cellulose and chitin). A group of one or more atoms bonded together.

What is a Crash Course?

Definition of crash course : a rapid and intense course of study also : an experience that resembles such a course has been given a crash course in diplomacy in his first weeks in office.

What is Crash Course for NEET?

A crash course is a short term course that students typically enrol for when an exam is just around the corner. The main purpose of such crash courses is to provide an overview, outline the entire course in a relatively lesser span of time, keeping in mind the time constraints.

Is Crash Course Biology reliable?

Most of the Crash Course videos are very accurate. However, in an effort to simplify content, some of the Crash Course Kids videos miss the mark. In "Vegetation Transformation," the video specifically states that carbon dioxide and water are turned into energy in sugar.

What are bio molecules give examples?

Explanation: The lifeless, complex organic molecules which combines in a specific manner to produce life or control biological reactions are called biomolecules. Examples => Carbohydrates, lipids (fats and oils), nucleic acids, enzymes.Oct 9, 2018

What are the three main biological molecules we eat?

Hank talks about the molecules that make up every living thing -- carbohydrates, lipids, and proteins -- and how we find them in our environment and in the food that we eat.

What is food Why do we eat food?

A food is something that provides nutrients. Nutrients are substances that provide: energy for activity, growth, and all functions of the body such as breathing, digesting food, and keeping warm; materials for the growth and repair of the body, and for keeping the immune system healthy.

What are the ingredients of life?

They are the ingredients for life, and we call them the carbohydrates, the lipids, the proteins, and the nucleic acids.

What are carbohydrates made of?

Carbohydrates are made up of sugars, and the simplest of them are called monosaccharides. "Mono" for one, "saccharides" for the actual root of the word sugar. The star of the show here is glucose, because it’s truly fundamental, by which I mean, like, number one on the global food chain, because it comes from the sun.

Why are Omega 3 fats important?

But the reason why these are important is because we can't synthesize them ourselves. They're essential fatty acids, meaning that we need to eat them in order to get them.

What are triglycerides and phospholipids?

So remember that triglycerides are three fatty acids connected to a glycerol. Swap one of those fatty acids out for a phosphate group, and you have a phospholipid. These make up cell membrane walls. Since that phosphate group gives that end a polarity, it’s attracted to water.

How are amino acids formed?

Amino acids form long chains called polypeptides. Proteins are formed when these polypeptides not only connect but elaborate and, frankly, really elegant structures. They fold. They coil. They twist. If they were sculptures, I would go the museum every day just to look at them, and I'd walk straight past the nudes without even looking.#N#But protein synthesis is only possible if you have all of the amino acids necessary, and there are nine of them that we can't make ourselves: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. By eating foods that are high in protein, we can digest them down into their base particles, and then use these essential amino acids in building up our own proteins. Some foods, especially ones that contain animal protein, have all of the essential amino acids, including this egg.

What is the process of getting energy from glucose?

And every cell that needs energy uses glucose to get that energy through a process called respiration. In addition to glucose, there are other monosaccharides like fructose, which has the same molecular formula (C 6 H 12 O 6) but arranged differently. These subtle chemical differences do matter.

What are the two main ingredients in fat?

Fats ( 07:47) Fats are made up mainly of two chemical ingredients: glycerol, which is a kind of alcohol; and fatty acids, which are long carbon-hydrogen chains that end in a carboxyl group. When you get three fatty acid molecules together and connect them to a glycerol, that’s a triglyceride.
