A research group has discovered an organism with cells that contain a previously undescribed organelle. They do some tests on th

e isolated organelle to see if it is involved in any major metabolic reactions. To do this, they incubate these organelles for a period of time and determine changes in the amount of various substances in the suspending solution. The results follow.
Glucose: None
CO2: Increase
O2: None
ATP: Increase
NADH: Increase


Based on this analysis, which part of cellular respiration do you conclude is taking place in this organelle?

A) pyruvate oxidation
B) citric acid cycle
C) glycolysis
D) electron transport chain/oxidative phosphorylation
E) glycolysis and the citric acid cycle

Answer:

B) citric acid cycle

Explanation:

Citric acid cycle or Krebs cycle is a part of cellular respiration and occurs in mitochondria in eukaryotes. In this process oxidation of acetyl-coA ( which comes from carbohydrates, fats and proteins) takes place and energy is released.

Along with acetyl-coA, water is also used and in the end NAD+ is reduced to NADH, ATP is produced and by product CO2 is generated. ATP is used as a source of energy. NADH also enters electron transport chain in next stage for production of more ATP.

The key to the evolution of altruism is that a. recipients have to be more likely to carry the altruistic allele than nonrecipie
cupoosta [38]

Answer:

The correct answer is b. actors have to be more likely to carry the altruistic allele than non actors.

Explanation:

Altruism is the behavior by an organism that benefits other organisms by costing its own fitness. The actor is the individual who is doing altruism and the recipient is the individual who is getting benefited by the actor's altruism.

An example of altruistic behavior can be seen in animal kingdom easily. Vampire bats give blood to those members of the community who were not able to go for search for blood show altruistic behavior.

Actors have altruistic genes that suggest them to behave altruistically. Non-actors may not contain alleles of altruism but the recipient might have altruistic alleles.

Hamilton's rule says that natural selection will favor the altruistic allele when rb > c.

where r = coefficient of relatedness between donor and recipient

          b = benefit received by recipient and

          c = cost paid by altruist.

Therefore, the correct answer is b.
