Why more atp is produced in aerobic respiration than in anaerobic respiration

Oxana [17]

Most of the ATP produced by aerobic cellular respiration is made by oxidative phosphorylation. This works by the energy released in the consumption of pyruvate being used to create a chemiosmotic potential by pumping protons across a membrane.

Aerobic metabolism is 19 times more efficient than anaerobic metabolism (which yields 2 mol ATP per 1 mol glucose). They share the initial pathway of glycolysis but aerobic metabolism continues with the Krebs cycle and oxidative phosphorylation. The post glycolytic reactions take place in the mitochondria in eukaryotic cells, and in the cytoplasm in prokaryotic cells.

True or false: single sugars are too large to be absorbed directly into the bloodstream

AleksandrR [38]

Answer:

False

Explanation:

The sugars on the basis of the number of glucose or sugar units can be categorized into two categories:

1. Simple sugars: The sugars which contain one or two sugar units called mono and disaccharides.

2. Complex sugars: The sugars which contain more than two sugar units are complex sugars.

The simple sugars like glucose, galactose are easily digested by the digestive system of the human body and easily absorbed by the cells.

Since the simple sugars or simple sugars are small in their structure compared to the complex carbohydrates therefore false is the correct answer.

Although carbon dioxide emissions are reduced geothermal power plants release odor pollution that smells like rotten eggs.

Temka [501]

The compound that smells like rotten egg is another pollutant, hydrogen sulfide with the chemical formula of H2S. This is specifically formed in the geothermal power plants because of the presence of the sulfur that when reacted with water or hydrogen may form the hydrogen sulfide.

In flies dumpy wings and ebony bodies are each mutations recessive to wild type, and you expect them to behave in a Mendelian fa

Dimas [21]

Answer:

See the answers below

Explanation:

Assuming that D (d) represents the allele for wing type and E (e) represents the allele for body type, crossing DdEe with DdEe will yield the following offspring according to the Punnet's square (see the attached image):

(a) 9/16 D_E_ wild type

3/16 D_ee wild wing, ebony body

3/16 ddE_ dumpy wing, wild body

1/16 ddee dumpy wing, ebony body

(b) Chi square $X^2$ = $\frac{(O - E)^2}{E}$ , where O = observed frequency and E = expected frequency.

Phenotype O E $X^2$

Wild type 473 9/16 x 830 = 466.875 $\frac{(473 - 466.875)^2}{466.875}$ = 0.08

wild w/ebony b 156 3/16 x 830 = 155.625 $\frac{(156 - 155.625)^2}{155.625}$ = 0.0009

Dumpy w/wild b 149 3/16 x 830 = 155.625 $\frac{(149 - 155.625)^2}{155.625}$ = 0.28

dumpy w/ebony b 52 1/16 x 830 = 51.875 $\frac{(52 - 51.875)^2}{51.875}$ = 0.0003

Total $X^2$ = 0.3612

Degree of freedom = 4 - 1 = 3

Tabulated value of $X^2$ (0.05)= 7.815

(c) Since the calculated Chi square value is less than the tabulated value, we conclude that the observed outcome agrees with the expected outcome and that the cross followed the standard Mendelian pattern.
