Biology
1 answer:
lisov135 [29]3 years ago

The answer is glucose and albumin. This is because they are fully reabsorbed back to the blood from the filtrate in the proximal tubule. Therefore evidence of traces of these molecules in urine during urinalysis is an indication of an underlying problem with the kidneys.

She notices that the muscle cells are loaded with mitochondria while the macrophages have abundant lysosomes. why is this so?
Kaylis [27]

The muscle cells are loaded with mitochondria to allow large amounts of ATP production while the macrophages have abundant lysosomes to digest the debris and dead organisms like bacteria.

Mitochondria are known as the powerhouse of a cell. This is because most of the ATP production used by various systems in their operation is produced by mitochondria. A chemical called NADH is produced in the mitochondrial matrix through the Krebs cycle. The enzymes embedded in the mitochondrial membrane use this chemical to produce Adenosine Triphosphate, generally known as ATP.

Macrophages are phagocytic white blood cells involved in engulfing and killing pathogens. They are involved in the innate immune response of the body. Lysosomes have specialized enzymes that can kill these pathogens.

Muscle cells need to contract or expand for which they require energy. Thus, they have abundant mitochondria. Whereas, the macrophages have abundant lysosomes to help them kill disease-causing pathogens like a virus or bacteria.

To know more about ATP production in mitochondria, refer to the following link:

The youth movement originated with the ___ the generation born after ___
VLD [36.1K]
I believe that the youth movement originated with the baby boomers, the huge generation born after the world war II. By 1970, 58.2 % of the population in America was under the age of 35 years. The economic boom of the 1950s meant more families could afford to send their children to College. College life gave the young people a sense of freedom and independence. It was on college campuses across the nation that youth protest movements began and reached their peak.
