Natali [406]3 years ago
6 0

Answer:

Mitochondria

Explanation:

This was the first endosymbiotic event during our primitive cell basically engulfed an aerobic bacteria which later formed into mitochondria. This is why mitochondria has its own DNA as well (called the mitochondrial DNA)

Which of the following kinds of cells preform basic functions such as obtaining energy from food?
strojnjashka [21]

Plant cells, but not animal cells

Animal cells, but not plant cells

Both plant cells and animal cells

Neither animal cells nor plant cells

Answer:

Both plant cells and animal cells

Explanation:

The process where the energy locked up in food is extracted take place in both plants and animal cells.This process is called Cellular respiration.It is the process of combining inhaled and diffused oxygen in the blood with assimilated food substances (glucose,amino acids,fatty acids and glycerol) to produce energy.

In both cells it takes place in the the cytoplasm and mitochondrial.

It begins with Glycolysis, followed by Krebs's Cycle..These two steps gives certain of ATPs to these cells

.However,the largest amount of ATPs is synthesized during oxidative phosphorylation  for maximum of energy to be produced.This process involved the chemiosmosis where protons were diffused into the intramembranes by the proton pump (PMF) and diffused back into the matrix of the mitochondria to generate the electrochemical gradients.

The electrochemical gradients generate the energy for enzymes ATPase synthase needed for phosphorylation of ADP with Pi to give ATPs.

The oxygen act act the final electron acceptor.

Alizarin yellow is a pH indicator that transitions from red to yellow when the pH falls from a value of 11 to below 10. Why is p
nydimaria [60]

Answer:

The correct answer is - acidic conditions wouldn't trigger a change in the color of Alizarin yellow.

Explanation:

The growth of E. coli generally occurs at neutral pH, however, its growth is normal at acidic conditions as well.  The change in the growth of  E. coli is not able to detect by alizarin.

The phenol red turns yellow in the presence of an acid, and the change in pH in an alkaline environment can be detected by the red color of phenol red. Growth of E.coli will grow in pH of 10-12 . But, very slowly. The color change in alizarin is also apparent at pH 10.2 to 12 only.
