Answer:

All four complexes pump protons out of the mitochondrial matrix

Explanation:

What differs are the biochemical processed by which each complex pumps out the protons. Only ATP synthase pumps proton from the intermembrane space to the matrix. This is as it harnesses the proton motive force, created by the other complexes, to generate ATP molecules.

natima [27]

The correct answer is a. Complex

A complex or undefined medium is rich in nutrients, which contain water-soluble extracts of plant or animal tissue, a sugar, (often glucose is added to serve as the main carbon and energy source). The combination of extracts and sugar creates a medium which is rich in minerals and organic nutrients, but the exact composition is unknown.

The number of cells in an average-sized adult human is on the order of 10^14 cells. Use this information, and the estimate that
KengaRu [80]
IF:
Number of cells: C = 10^{14}
DNA lenght: D = 2m = 12.42 * 10^{-4} mi
Distance from Earth to Sun: ES=93000000 mi = 9.3* 10^{7}mi

Then:
a) <span>Over how many miles would the total DNA from the average human stretch?
The answer is product of multiplication of the number of cells (C) and the DNA length (D):
Total DNA: </span>T = C*D
              ⇒ T = 10^{14}*12.42* 10^{-4} mi
              ⇒ T = 12.42* 10^{14-4} mi
              ⇒ T = 12.42* 10^{10} mi
The total DNA from the average human will stretch 12.42* 10^{10} mi

b) How many times would the total DNA from the average human stretch from Earth to the Sun and back?
The answer is concluded from the ratio of the total DNA length (T) and the <em>twice </em>(because of stretch to the Sun and back, thus, <em>two directions</em>) of distance from <span>Earth to the Sun (ES) and :
Ratio: </span>R= \frac{T}{2*ES}
      ⇒ R = \frac{12.42* 10^{10}mi }{2*(9.3* 10^{7}mi)}
      ⇒ R = \frac{12.42* 10^{10}}{18.6*10^{7}}
      ⇒ R = 0.6677* 10^{10-7}
<span>      ⇒ R = 0.6677* 10^{3}
</span><span>      ⇒ [tex]R = 667.7
</span>Thus, 667,7 times will the <span>total DNA from the average human stretch from Earth to the Sun and back.</span>

Full localization, discrimination of intensity, and interpretation of somatosensory stimuli requires processing by the:
wariber [46]

Answer: Somatosensory cortex.

Explanation: The somatosensory cortex receives all sensory input from the body. The somatosensory system is a part of the <u>sensory nervous system</u>. These sensory receptor cells are activated by different stimuli such as heat and nociception, giving a functional name to the responding <u>sensory neuron</u>, such as a thermoreceptor which carries information about temperature changes.
