A scientist performs a series of mutation screens to look for mutations that reduce ATP production. One of the mutants, compared to a wild-type cell, has reduced levels of ATP and NADH and increased levels of FAD and pyruvate. Which hypothesis best fits these observations?

Answers

The hypothesis that best fits the observation that one of the mutants has reduced levels of ATP and NADH and increased levels of FAD and pyruvate is that the mutation is disrupting the citric acid cycle (Option 3).

What is the citric acid cycle?

The citric acid cycle, also known as the Krebs cycle, is the second step of cellular respiration which is required to generate ATP through the oxidation of pyruvate.

The reduced form of Nicotinamide adenine dinucleotide (NADH) produced during the citric acid cycle is then used in oxidative phosphorylation (the third step of cellular respiration) in order to generate more ATP.

Therefore, with this data, we can see that the citric acid cycle generates the reduced form of Nicotinamide adenine dinucleotide (NADH) and thus increases the production of ATP, thereby a mutation in an enzyme that works in this pathway may also hamper the proportion of ATP.

I took the quiz :)

The organisms that belong to the Prokaryotic domain of life and it comes in three different shapes, such as cocci, rods, and spirals are known as Eubacteria.

What do you mean by the Prokaryotic domain?

The prokaryotic domain may be characterized as the kingdom of Prokaryotes is significantly made up of two domains namely, Archaea and Bacteria. These eubacteria are classified under the domain of bacteria which is represented by the relation based on the DNA experimental approach.

According to the context of this question, there are mainly three types of eubacteria commonly found. They are round (coccus), rod-like (bacillus), comma-shaped (vibrio), or spiral. All these types of different body plans, structures, and functions with respect to their morphology.

Therefore, eubacterium is a type of organism that belongs to the Prokaryotic domain of life and it comes in three different shapes, such as cocci, rod, and spiral.

In experiments with competitive barnacle species distributed along upper and lower intertidal zones, researchers found a trade-off between ability to _____ and ability to _____.

Answers

In this case, researchers observed a trade-off between the ability to tolerate harsh dry conditions and the ability to colonize deeper water. This type of trade-off can increase the fitness of only one phenotypic trait.

An evolutionary trade-off can be defined as an evolutionary mechanism where a trait can increase its adaptive fitness in the detriment of decreased adaptive fitness in another phenotypic trait.

In trade-offs, the evolutionary adaptive processes cannot optimize a given trait without compromising another.

A well-known example of an evolutionary trade-off is the balance between the number of eggs that a bird can produce in a determined clutch.
