AboutTranscript. Lysosomes, the cell's recycling centers, use acid hydrolases to break down waste into reusable parts through autophagy and crinophagy. Peroxisomes protect cells by isolating and breaking down harmful hydrogen peroxide into water and oxygen. These organelles ensure efficient and safe cellular function. Controlling glucose levels is essential for energy production and storage and for proper maintenance of blood glucose levels. The body has come up with an elegant way to utilize many of the same enzymes to produce and break down glucose.

Video transcript. - Let's talk about microtubules in more detail. So, first we'll discuss the structure. So, microtubules are made up of two proteins. The first is called alphatubulin, and the second similar protein is called betatubulin, and the alphatubulin and betatubulin will join together to form a dimer. A dimer's simply when you have two ... Heat (Q), however, is the transfer of energy due to a difference in temperature. So an object cannot "have" heat. It is one of two ways you can transfer energy between the system and the surroundings. The other is work (W), which is mechanical transfer of energy, and that relationship is described by the First Law of Thermodynamics: delta (U ...

The pancreas, located behind the liver, has a unique blood supply that triggers hormone release. It houses insulin and glucagon in structured cells called the islet of langerhans. Beta cells release insulin while alpha cells release glucagon. The process of insulin release involves glucose, ATP, potassium, and calcium.

Amino acids are the building blocks of proteins. They contain an amino group, carboxylic acid group, alpha carbon, and side chain. Most amino acids have a chiral carbon, which allows them to rotate polarized light. Amino acids can have either an L- or D- configuration, but only the L- form is found in the human body.
