Answer 1

Answer-

According to the given question-

Question 15-

Oxidation- defined as addition of oxygen or loss of electron from ion or atom and increases the oxidation number of ion or atom.

Reduction- gain of electron is called reduction.

Oxidation Cu to Cu? Lecce CH, CHC-H to CH, CH2C-OH с ноос, но, с но, во со

Reduction Fet to Fe ubiquinone (akctone) to ubiquinol (an alcohol) 2 Ago 2 A NO, to NO; CH,CH,OH to CH.CH

Question 7-

in 00 Cell type ATP (mM) ADP (M) P, (mm) liver muscle brain 0.7

AG=AG* + RT In (Koq)

$\triangle$G'' = - 30.5 KJ mol-1

RT = 2.47 KJ mol-1

Keq  = [ADP] eq $\times$ [Pi]  $\div$ [ATP]

For liver

Keq = 1.8 $\times$ 5.0 $\div$ 3.5 = 2.571

For muscle

Keq = 8.0 $\times$ 0.9  $\div$ 8.0= 0.90

For Brain

Keq = 2.6 $\times$ 0.7 $\div$ 2.7 = 0.674

putting these valve in given equation -

For Liver-

$\triangle$G = -30.5 + 2.47 $\times$ $\ln$ 2.571

= -30.5 + 2.47 $\times$ 0.94

= -30.5 + 2.32

$\triangle$G = - 28.18

For muscle

$\triangle$G = -30.5 + 2.47 $\times$ $\ln$ 0.90

= -30.5 + 2.47 $\times$ (-0.105)

= - 30.5 - 0.26

$\triangle$G= - 30.76

For Brain

$\triangle$G = -30.5 + 2.47 $\times$ $\ln$ 0.674

= -30.5 + 2.47 $\times$ (-0.394)

= - 30.5 - 0.97

$\triangle$G= - 31.47

So for Liver   $\triangle$G = - 28.18

Muscle $\triangle$ G= - 30.76

Brain  $\triangle$G= - 31.47

Most energy released by cell present in Brain followed by Muscle followed by liver

Brain  $\triangle$G= - 31.47 > Muscle $\triangle$ G= - 30.76 > Liver  ​​​​​​​ $\triangle$ G = - 28.18/
