the concentration of h+ ions inside the mitochondrial matrix is lower than it is in the cytosol or the mitochondrial intermembrane space. what would be the immediate effect of a membrane-permeable compound that carries and releases protons into the mitochondrial matrix?

Answers

The immediate effect of a membrane-permeable compound that carries and releases H+ into the mitochondrial matrix would be the inhibition of ATP synthesis. This process (ATP synthesis) requires an H+ gradient.

Mitochondria are the energy center of the eukaryotic cells, which generate energy in the form of ATP by a process called cellular respiration.

Cellular respiration has three main phases: glycolysis, the Krebs cycle and oxidative phosphorylation

During oxidative phosphorylation, a chain of transport of electrons across the inner mitochondrial membrane is coupled to the generation of an electrochemical proton (H+) gradient, which is used to synthesize ATP.

This electrochemical gradient is created by pumping H+ from the matrix to the inner membrane space of the mitochondria.

Answers

Answer: low blood sodium concentration, net movement of free water, increased matrix pressure, abnormal neuron firing rate, seizures

Explanation:

convulsions, aberrant neuron firing rate, elevated matrix pressure, low blood sodium levels, and net free water movement.

What is clark’s seizures?

The depth of melanoma as it develops in the skin is described by a staging method called the Clark Level. In addition to or instead of a stage, your doctor could assign you a melanoma level.

Due to overhydration, Clark is currently experiencing seizures. Students "fly into" Clark's brain to investigate crucial components of the environment in an effort to ascertain what is triggering the seizures.

increased Na concentration in the brain's matrix caused blood water to enter the brain, raising the matrix pressure. The likelihood of seizures rose as a result of pressure increasing the pace at which neurons fired.

Overhydration may happen in a variety of clinical circumstances. Acute plasma osmolality lowering causes brain swelling due to passive water influx.

Thus, convulsions, aberrant neuron firing rate, elevated matrix pressure.

A diagram of chloroplast stroma and thylakoid lumen showing chemical energy, ferredoxin, ferredoxin-N A D p reductase, A D P synthase, and oxygen-evolving complex. Which corrections would change the diagram to accurately model the light-dependent reaction of photosynthesis? Check all that apply. CO2 should be changed to H2O. ADP and ATP need to be switched. e– should be changed to H . Chemical energy should be changed to light energy. PSII and PSI need to be switched.

Answers

Given the process of photosynthesis is used to produce ATP in the presence of light and water, the first, second, and fourth options are what need to be changed.

Photosynthesis is the process by which certain organisms transform light energy into chemical energy in the form of ATP. The first option states that CO2 should be changed to H2O, which is correct. This is due to the fact that photosynthesis oxidizes H2O in order to produce a molecule of oxygen.

Option 2 is also correct in that the diagram should show ATP instead of ADP, given that photosynthesis is used by organisms to produce ATP as the primary energy product. To carry out the function, the enzyme used is ATP synthase, which is what the diagram should reflect.

Finally, we should also choose option 4, which states that chemical energy should be switched with light energy. As previously states, photosynthesis uses light energy to produce chemical energy. Though chemical energy is produced, it is the final product and does not participate in the process, light energy does.

you want to arrange digits 0 to 9 such that 1 and 2 always have 2 digits between them

Answers

We want to arrange digits 0 to 9 such that 1 and 2 always have 2 digits between them (we want to find the number of different combinations to do this).

There are 564,480 ways of arranging the digits 0 to 9 in such a way that there is always 2 digits between 1 and 2.

Now let's see how to get the number of combinations.

We have 10 numbers to order, so we have 10 places to put these numbers.

_ _ _ _ _ _ _ _ _ _

Let's start by assuming that the first number is the 1

1 _ _ _ _ _ _ _ _ _

Because 1 and 2 must have 2 digits between them, we put the 2 in the third place

1 _ _ 2 _ _ _ _ _ _

Now in the other 8 places we can put any of the other 8 numbers in any order, The number of combinations is just given by:

8! = 8*7*6*5*4*3*2*1 = 40,320

Now we also need to take in account the permutations of the 1 and the 2.

First, these two can permute (so the 2 goes first and then the 1) so there is a factor 2.

Also, we fixed the first one at the first position, but it could be in the second, third, fourth, fifth, sixth or seventh position, so there is also a factor 7.

Then the total number of combinations is given by:

2*7*40,320 = 564,480

This means that there are 564,480 ways of arranging the digits 0 to 9 in such a way that there is always 2 digits between 1 and 2.

what is the average rate of change of y = cos (2x) on the interval [0, π2]?

Answers

The average rate of change of the function y = cos(2x) over the interval (0, π/2) is [tex] \frac{-4}{\pi}[/tex]

The average rate of change over a given interval is defined thus :

[tex] R = \frac{f(b) - f(a)}{b - a}[/tex]

Where a and b are the interval values

At a = 0 :

f(0) = cos(2(0)) = Cos 0 = 1

At b = π/2 :

f(π/2) = cos(2(π/2)) = Cos π = - 1

Hence,

[tex] \frac{f(b) - f(a)}{b - a} = \frac{-1-1)}{\frac{\pi}{2} - 0} = \frac{-2}{\frac{\pi}{2}} = \frac{-4}{\pi} [/tex]

Therefore, the average rate of change over the interval is [tex] \frac{-4}{\pi}[/tex]
