Answer:
A. proton-driven rotation of the Fo subunit, which causes F1 to change conformation due to that rotation, allowing ADP to be phosphorylated to ATP
Explanation:
To answer the question we need to understand the following.
What is ATP synthase?
- ATP synthase is an enzyme that is found in the electron transport chain which is the final phase of cellular respiration.
What is the Role of ATP synthase?
- The role of ATP synthase is to synthesize ATP which is the main storage energy molecule in the cells.
How does ATP synthase allow production of ATP?
- Production of ATP by ATP synthase complex is through oxidative level phosphorylation.
- The flow of protons down the concentration gradient into the mitochondrion matrix through ATP synthase. This drives the rotation of ATP synthase thus catalyzing the phosphorylation of ADP to ATP.
Answer:
0.00479 volts
Explanation:
From Faraday's law of electromagnetic induction, the induced emf equals the change in magnitude flux (magnetic field strength multiplied by the area = BA) divided by the time change
Therefore we have the equation
EMF = BA÷t
Since area A = 2πr
EMF = Bπr²÷t
B = 5.5×10^(-5)
Velocity = 100km/h = 27.7778m/s
r = 1m, t = r÷V = 0.036
EMF = Bπr²÷t = (5.5×10^(-5) x π x (1)²)÷0.036 = 0.00479 Volts
<u>The answer is not contained detail explanation, just a solution and the required values. </u>
All the details are in the pictures, the answers are marked with orange colour.
Note,
in the task no 20.:
V - the velocity of the pair of the balls after collision.
in the task no 21:
m₁ - the mass of the copper ball; m₂ - the mass of the copper calorimeter; m₃ - the mass of the water; t₀ - the initial temperature of water in the copper calorimeter; θ - the final temperature in the calorimeter after the copper ball is transferred into a copper calorimeter; t₁ - the required initial temperature of the copper ball before it is transferred into the calorimeter.
Answer:
<h2><u>
The capacity or power to do work/ The ability to do work. </u></h2>
Explanation:
such as the capacity to move an object (of a given mass) by the application of force. Energy can exist in a variety of forms, such as electrical, mechanical, chemical, thermal, or nuclear, and can be transformed from one form to another
I hope this help:)
Answer:
the charge carriers have an energy 2.8 10⁻¹⁹ J
Explanation:
The energy in a diode is conserved so the energy supplied must be equal to the energy emitted in the form of photons.
The energy of a photon is given by the Planck expression
E = h f
the speed of light, wavelength and frequency are related
c = λ f
we substitute
E = 
a red photon has a wavelength of lam = 700 nm = 700 10⁻⁹ m
we calculate the energy
E = 6.626 10⁻³⁴ 3 10⁸/700 10⁻⁹
E = 2.8397 10⁻¹⁹J
therefore the charge carriers have an energy 2.8 10⁻¹⁹ J,
