Explanation

The electron transport cycle generates around 30–32 ATP molecules

Both photosynthesis and cellular respiration take place in mitochondria.

By transferring electrons from NADH and FADH2 through a series of complexes and electron carriers, these carriers ultimately produce ATP.

Explanation

The enthalpy is defined by H = E + pV for a change in the states of a system.

ΔH = Δ (E + pV) = ΔE + Δ (pV) = ΔE + pΔV + VΔp 

Enthalpy, H, is a thermodynamic property that describes the heat lost or gained in a system.

The change in enthalpy, ΔH, is equal to the sum of the change in internal energy, ΔU, plus the product of the constant pressure, P, and the change in volume, ΔV.

Explanation

He lives in an old house

 before the +ve degree adjective, we should use " an or a"

 old is the adjective and vowel so we select the option " an"

Explanation

s-orbital has only one magnetic quantum number which is 1, meaning it only has one possible orientation.

while

There are five different orientations of the d orbitals

p orbital has 3 orientations: px,py&pz

f-orbital has 7 orientations.

Explanation

r = n^2 x 0.529 A

r = 3^2 x 0.529 A

r = 9 x 0.529 A

Explanation

Maleic-fumaric acid shows cis-trans isomerism.

Maleic acid is the cis-isomer of butenedioic acid

whereas fumaric acid is the trans-isomer.

Explanation

Its cyclic structure consists of 5-membered rings similar to furanose.

Thus it is also called D-Ribofuranose.

Explanation

The noun 'boy' is not a proper noun.

A Few examples of proper nouns are India, January, Christmas, Monday, Alex, Meera, etc.

A Few examples of common nouns are table, chair, book, boy, girl, bedroom, school, college, etc.

Explanation

An enzyme called hexokinase uses the energy of ATP to add a phosphate group to glucose to form glucose-6-phosphate.

Explanation

At equilibrium, the rate of forward reaction is equal to the rate of backward reaction.

This is as per the definition of the equilibrium.

When a reversible reaction is carried out in a closed vessel, a stage is reached when the forward and the backward reactions proceed with the same speed.
