How many CO2 molecules are produced when three glucose molecules undergo cellular respiration? Explan ​

Answers

Answer:

18 molecules of CO_(2)

Explanation:

In heterotrophic nutrition, organisms ingest or absorb food made by autotrophs to obtain energy. Planta and other photosynthesizing organisms make sugars via photosynthesis, in a form of (partly) light-dependent biosynthesis.

In mitochondria, they break down sugars through aerobic respiration. For the sugar glucose, this results in the production of carbon dioxide and water along with energy in the form of ATP or adenosine triphosphate.  

C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP

glucose+ oxygen →  carbon dioxide+ water+ energy

For 3 molecules of glucose, multiply the number of reactants and products...

(C6H12O6+ 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP ) x 3

Thus...

3 C6H12O6+ 18 O2 → 18 CO2 + 18 H2O + ≅114 ATP

Why do allele frequencies give us genetic variation

Answers

Answer:

why are The more variation a population has, the better its ability to adapt to changes in its environment through natural selection. If there is more variation, the odds are better that there will be some alleles already present that allow organisms to survive and reproduce effectively under the new conditions

Explanation:

Note the mechanism of absorption (passive or active transport) of the following food breakdown products, and indicate by a check mark whether the absorption would result in their movement into the blood capillaries of the lymphatic capillaries (lacteals).Substance Mechanism of absorption Blood Lymph
Monosaccharides
Fatty acids and glycerol
Amino acids
Water
Ca2+ , Na+ , Ca2+

Answers

Answer:

The absorption of monosaccharides takes place via facilitated and cotransport mechanism and is transported through blood capillaries present in the villi.  

The absorption of glycerol and fatty acids takes place through diffusion and the majority of them are transported via lymph capillaries, while some are transported through blood capillaries.  

The absorption of amino acids takes place via a cotransport mechanism with sodium ions and is transported through blood capillaries.  

The absorption of water takes place by the process of osmosis via diffusion and is transported with the help of blood capillaries.  

The absorption of calcium and sodium ions takes place via an active transport mechanism, while the absorption of chlorine takes place via the process of diffusion. The transportation of all these ions takes place with the help of blood capillaries.  

Final answer:

Monosaccharides, amino acids and ions are generally absorbed through active transport into the blood capillaries, while fatty acids and glycerol are transported into the lymphatic capillaries. Water is absorbed via osmosis into both the blood and lymph capillaries.

Explanation:

The absorption mechanisms of the various food breakdown products are different and determine whether they move into the blood capillaries or into the lymphatic capillaries. This absorption is either through passive or active transport.

  • Monosaccharides like glucose are absorbed through active transport into the blood capillaries.
  • Fatty acids and glycerol are also absorbed into the cells lining the small intestine, they are then reassembled into fats and transported into the lymphatic capillaries.
  • Amino acids are absorbed through active transport into the blood capillaries.
  • Water is absorbed mainly via osmosis, a type of passive transport, into both the blood and lymph capillaries.
  • Ions (Ca2+, Na+, Ca2+) are absorbed through active transport into the blood capillaries.

Which three of the statements are true? A. Amphipathic (amphiphilic) lipids are the structural basis of biological bilayer membranes.
B. The tendency of water to minimize its contact with nonpolar substances is called the hydrophobic effect.
C. Hydrophobic molecules are individually hydrated in water, increasing the entropy of the system.
D. Hydrophobic molecules clump together in water because fewer water molecules are required to surround them, which results in a smaller decrease in entropy than if the molecules were individually hydrated.
E. Nonpolar molecules are capable of forming micelles.

Answers

Answer:

Answer : A, B and D

Explanation:

Amphipathic lipids are lipids that have bothe polar and non-polar parts or end. The polar part is the part which is described as hydrophilic i.e water loving, while the non-polar part is described as hydrophobic, meaning water fearing.

Most or all hydrophobic molecules clump together in water in order to prevent water from surrounding the molecules. This means that, they do not break the hydrogen bond in the water. This is known as hydrophobic effect.

In this case, it will be discovered or concluded that, the three options, A, B and D, are the statements that are considered to be true.

Answer:

The three of the statements which are true includes A,B,and D.

A. Amphipathic (amphiphilic) lipids are the structural basis of biological bilayer membranes.

B. The tendency of water to minimize its contact with nonpolar substances is called the hydrophobic effect.

D.Hydrophobic molecules clump together in water because fewer water molecules are required to surround them, which results in a smaller decrease in entropy than if the molecules were individually hydrated.

Explanation: option E is wrong because micelles are formed by amphipathic molecules like Lipids not non polar molecules. Option C is wrong because water molecules involved in hydration cannot participate in normal hydrogen bonding with one another.

How doe vertical farming work

Answers

Vertical farming is exactly what it sounds like: a way of farming on vertical surfaces rather than traditional, horizontal farming. By using vertically stacked layers, farmers can produce a great deal more food on the same amount of land.

Determine if the equations represent synthesis reaction, decomposition reaction, single displacement reaction, or double displacement reactions .

Answers

The reaction of calciumsulfate is double displacement reaction, the reaction of copper and oxygen is synthesis reaction. The reaction of copper oxide and oxygen is single displacement reaction.

What is chemical reaction?

When atoms establish or break chemicalbonds, chemical processes take place. Reactants are the substances that begin a chemical reaction, while products are the compounds that are created as a result of the reaction.

Combination, decomposition, single-replacement, double-replacement, and combustion are the five fundamental types of chemicalreactions. You can classify a reaction into one of these groups by looking at the reactants and products.

Calcium sulphate undergoes a doubledisplacement reaction, whereas copper and oxygen undergo a synthesis reaction. Copper oxide and carbon is single  displacement reaction.

Thus, first is double displacement reaction, second is synthesis reaction, as well as third reaction is single displacement reaction.
