How does eukaryotic cellular division differ from prokaryotic?

Biology
1 answer:
Feliz [49]3 years ago
6 0
Prokaryotic cells are simpler than eukaryotic cells. This is because prokaryotic cells have  a single circular chromosome, no nucleus, and few other organelles. Eukaryotic cells have many chromosomes inside a nucleus, and they also have more organelles.

The net energy yield from this pathway, where glucose is broken down through several steps forming pyruvate, is ________ molecul
stepan [7]

Answer:

2 molecules of ATP and 2 molecules of NADH

Explanation:

Glycolysis is the first step of cellular respiration (break down of glucose to extract energy) which occurs in the cytoplasm. Glycolysis is a pathway common to all living organisms- prokaryotes and eukaryotes, as it does not require oxygen to occur.

Glycolysis occurs in two major phases (ten steps) requiring 10 enzymes catalyzing each step; the energy-requiring phase and the energy-requiring phase.

In the energy-requiring phase, the starting molecule (glucose) gets rearranged in a series of chemical reactions, and two phosphate groups gets attached to it producing fructose-1,6-bisphosphate which is unstable, This modified sugar then splits in half due to its instability to form two different but inter-convertible phosphate-bearing three-carbon sugars (Dihydroxyacetonephosphate, DHAP and Glyceraldehyde-3-phosphate, G3P). Because the phosphates used in these steps come from 2 ATP molecules, 2 ATP molecules get used up in this phase

All the DHAP molecules get converted to G-3-P in order to enter the next phase.

In the energy-recovering phase, the 3-carbon sugar (G3P) is converted into another three-carbon molecule called pyruvate, through a series of reactions. In these reactions, two ATP and 1 NADH molecules are made. This recovery phase occurs twice (one for each of the two isomeric three-carbon sugars, DHAP and G3P). Hence, a total of 4 ATP and 2 NADH molecules are produced in this phase.

Overall, Glycolysis converts one glucose (six-carbon) molecule to two pyruvate (three-carbon) molecules and a net release of 2 ATP molecules (4 overall - 2 used) and 2 NADH molecules.

7. It is a criticism of many population ecologists that the pattern of population increase
Komok [63]

Answer: Disagree

Explanation:

I tend to disagree with this statement because predators actually have a place in ecosystems to keep prey species from becoming overpopulated, hence, the extent of the overpopulation would likely have been much less if the natural predators were allowed to play a role in controlling the deer population.
