If CPR is not performed, how many minutes will elapse before the brain becomes damaged from lack of oxygen?
attashe74 [19]
If CPR is not performed, C. 4 minutes will elapse before the brain becomes damaged from lack of oxygen.
One minute isn't enough time - you can even hold your breath for one minute without fainting. Some people can even do it for 2 minutes.
Ten minutes is too long - you would be long dead.

I have mutant cells that make no pfk2enzyme. i measure rates of oxygen consumption in these mutant cells and compare them to wil
Kazeer [188]

The correct answer is that mutant cells will exhibit diminished oxygen consumption; decreased glycolysis results in decreased Kreb's cycle and electron transport chain.

The PFK2 enzyme catalyzes the generation of F26BP, this binds with the allosteric site of PFK-1 and increases the affinity of PFK-1 with F6P and also decreases the affinity of allosteric inhibitors citrate and ATP to PFK-1. Thus, PFK-1 will combine with F6P at a greater rate.

This ultimately results in more glycolysis, thus, more ETC and more consumption of O2. If there is no PFK2, then there will be a reduction in glycolysis, TCA, ETC, and consumption of oxygen.

The PFK2 is an enzyme accountable for monitoring the rates of gluconeogenesis and glycolysis in the human body. In the absence of glycolysis, there will be a reduction in TCA, ETC, and consumption of O2.

What is the basic unit of classification and is denoted by a unique two-part scientific name?.
ludmilkaskok [199]

Species is the basic unit of classification denoted by a unique two-part scientific name.

<h3>What is meant by species? </h3>

Species is a name given to a group of organisms which have similar individuals. They are capable of reproducing among themselves and thus exchanging genes among themselves.

Species is the lowest of taxa and is thus the most basic unit of classification. Genus is the next taxonomic rank of the next taxa on the hierarchy of classification.

It is estimated that on earth, there are 8.7 million species living currently. This concept of species is from the times of Aristotle.

Therefore, species is the basic unit of classification denoted by a unique two-part scientific name.
