Hypothesize whether prokaryotic cells might have been symbiotic before the evolution of eukaryotic

1 answer:

4 0

Some scientists hypothesize that the eukaryotic cells are really the result of symbiotic processes!

Specifically, the internal organs of the cells could be a remnant of a symbiotic relationship in which one cell lived inside of another cell. These two cells then both split upon reproduction and eventually the cell inside was reduced to an organelle.

But according to this theory, it is very likely that the prokaryotic cells engaged in a number of symbiotic relationship, and that this actually lead to the emergence of eukaryotic cells!

Answer

Cells use the hydrolysis of adenosine triphosphate, abbreviated as ATP, as a source of energy. Symbolically, this reaction can be written as

$ATP(aq)+H_{2}0(l)- > ADP(aq)+H_{2} PO\frac{}{4} (aq)$

where ADP represents adenosine diphosphate. For this reaction, a. Calculate at b. If all the free energy from the metabolism of glucose

$C_{6} H_{12}O_6(s)+6O_2(g)- > 6CO_2(g)+6H_2O(l)$

goes into forming ATP from ADP, how many ATP molecules can be produced for every molecule of glucose?

$C_6H_1_2O_6(s)+O_2(g)- > 6CO_2(g)+6H_2O(l)$

goes into forming ATP from ADP, how many ATP molecules can be produced for every molecule of glucose?

Vivianne is motivated and ready to lose weight that she has gained over the past 20 years. Which of the following are appropropr

ElenaW [278]

Answer: Eat more nutrient-dense foods

Reduce intake of saturated fats

Eat more fruits and vegetables

Explanation:

Eat more nutrient-dense foods: The food rich in fibers, proteins, and other nutrient-based food will provide strength to the body and will also support the weight loss by stopping the tendency of frequent eating by increasing the mass of food that one eats.

Reduce intake of saturated fats: Saturated fat tends to increase the low-density lipoproteins or bad cholesterol in the body. This LDL will increase the cholesterol level in the body and will cause an increase in weight gain.

Eat more fruits and vegetables: Fruits and vegetables are a good source of fibers, which will keep the stomach full for a long time. Thus will reduce the dependency on high fat-containing food.
