Identify the reactions of the citric acid cycle that provide reducing power for the electron‑transport chain

svet-max [94.6K]

The reactions of the citric acid cycle that provide reducing power for the electron‑transport chain are as follows:

Conversion of isocitrate to α-ketoglutarate
Conversion of succinate to fumarate
Conversion of α-ketoglutarate to succinyl-coA

<h3>What is citric acid cycle?</h3>

Citric acid cycle also known as kreb cycle is a series of biochemical reactions that involves the synthesis of reduced electron carrier and ATP.

The following steps in the citric acid cycle involves the provision of reducing power for the electron‑transport chain:

Conversion of isocitrate to α-ketoglutarate: Isocitrate is converted to α-ketoglutarate as catalyzed by isocitrate dehydrogenase.
Conversion of α-ketoglutarate to succinyl-coA: α-ketoglutarate is converted to succinyl-coA as catalyzed by α-ketoglutarate dehydrogenase.

A cube with sides of area 18 cm^2 contains a 6.0 nanoCoulomb charge. Find the flux of the electric field through the surface of

Vanyuwa [196]

Answer:

The flux of the electric field is 677.6 Nm²/C

Explanation:

Given that,

Area = 18 cm²

Charge = 6.0 nC

We need to calculate the flux of the electric field

Using Gauss's law

$\phi=\dfrac{q}{\epsilon_{0}}$

Where, q = charge

$\epsilon_{0}$ =permittivity of free space

Put the value into the formula

$\phi=\dfrac{6.0\times10^{-9}}{8.854\times10^{-12}}$

$\phi=677.6\ Nm^2/C$

Hence, The flux of the electric field is 677.6 Nm²/C.

A horizontal disk with a radius of 23 m rotates about a vertical axis through its center. The disk starts from rest and has a co

lys-0071 [83]

Answer:

time is 0.42 sec

Explanation:

Given data

radius = 23 m

angular acceleration = 5.7 rad/s²

to find out

time

solution

we know that radius is constant so that

tangential acceleration At = angular acceleration × radius ............. 1

tangential acceleration = 5.7 × 23 = 131.1 m/s²

and

radial acceleration Ar = (angular velocity)² × radius ........................2

we consider angular velocity = ω

this is acting toward center

compare 1 and 2

At = Ar

5.7 r =ω³ r

ω = √5.7 = 2.38746 rad/s

ω = 5.7 t

2.387 = 5.7 t

t = 2.387 / 5.7

t = 0.4187

time is 0.42 sec

Can someone help me?!!!!!

babunello [35]

Answer:

56 m/s

Explanation:

The time we are considering is

t = 15 s

The vertical velocity of the projectile is given by

$v_y(t) = v_{0y}-gt$

where

$v_{0y}=100 m/s$ is the initial vertical velocity

$g=9.8 m/s^2$ is the acceleration due to gravity

Substituting t=15 s, we find the vertical velocity of the projectile at that time:

$v_y = 100 m/s - (9.8 m/s^2)(15 s)=-47 m/s$

where the negative sign means the direction is now downward.

The horizontal velocity does not change since there are no forces acting along that direction, so it remains constant:

$v_x = 30 m/s$

So, the magnitude of the velocity at the moment of impact is

$v=\sqrt{v_x^2 +v_y^2}=\sqrt{(30 m/s)^2+(-47 m/s)^2}=55.8 m/s \sim 56 m/s$
