The prosperity of the boom years led to the extravagant lifestyles for the wealthy which eventually led to the collapse of the w

NemiM [27]

To a large extent, this statement is true. The 1920s was a period in history in which extravagant lifestyles were the norm for the wealthy. People began to engage in mass consumption and consumerism. This led to overspending and to luxurious lifestyles, as the country experienced an economic boom.

This also led to people wanting to become rich quickly by speculating in the stock market. The financial decisions made during this era eventually led to the Wall Street Stock Crash of 1929, which led to the Great Depression of the 1930s.

During the Great Depression, many people lost their jobs, millions became poor and many others relocated to cities to look for work. The Great Depression led to the passage of several acts that promoted social welfare, which were collectively known as the "New Deal."

There has been a mix-up in the lab, and you have been asked to decipher which vial of cell-free extract is from which experiment

USPshnik [31]

The citric acid cycle can be associated with the first vial. Glycolysis can be associated with the second vial. The chemiosmosis can be combined with the third vial and the electron transport chain can be combined with the fourth vial.

We can arrive at this answer because:

The citric acid cycle is called the Krebs Cycle. Oxaloacetate is an intermediate compound in the Krebs cycle. The first vial has a high concentration of oxaloacetate and therefore we can associate it with the citric acid cycle.

Pyruvate is the end product of glycolysis and has a high concentration in the second vial, which can be associated with glycolysis.

The electron transport chain produces a large amount of ATP, which can be associated with the fourth vial which contains a large concentration of ATP.

Chemosmosis is the movement of ions across the plasma membrane. It does not produce, nor does it promote a high concentration of any element, which justifies our association in the third vial.

The vial and the products they contain can be seen in the figure below.
