When there isn't enough oxygen for Oxidative Phosphorylation to occur, anaerobic respiration occurs. You can't produce ATP across the inner of the mitochondrial membrane or in the Krebs cycle if you don't have Oxidative Phosphorylation. As a result, the yeast employs anaerobic respiration to keep Glycolysis running, resulting in 4 ATP molecules (Net: 2) each Glucose molecule that is converted to Pyruvate.
Allowing NADH to lose hydrogen allows it to be converted to NAD, which can then be utilized to oxidize glucose to pyruvate, which produces ATP, and so on. This is best illustrated in a diagram, in my opinion.
Answer:
77 L of water can be made.
Explanation:
Molar mass of 
= 32 g/mol
So, 55 g of = 
mol of = 1.72 mol of
As hydrogen is present in excess amount therefore is the limiting reagent.
According to balanced equation, 1 mol of produces 2 mol of 
.
So, 1.72 mol of produce 
mol of or 3.44 mol of .
Let's assume gas behaves ideally at STP.
Then, 
, where P, V, n, R and T represents pressure, volume, no. of moles, gas constant and temperature in kelvin scale respectively.
At STP, pressure is 1 atm and T is 273 K.
Here, 
= 3.44 mol and R = 0.0821 L.atm/(mol.K)
So, 
Option (b) is correct.
Answer:
The pendulum will begin to swing in the direction of the unbalanced force
Explanation:
The action of an unbalanced force on a pendulum will cause the pendulum to go into oscillation.
It must be stated that an unbalanced force causes acceleration of an object, in the direction of that force. Hence, unbalanced forces always set an object in motion.
Answer: Hydrochloric acid poses a various health risk
Answer:
Concentration of original solution = 1.66
Explanation:
We know that
We have given concentration of NaOH = 0.1678
Volume of NaOH = 19.88 mL = 0.01988 L
So moles of NaOH = volume x concentration of NaOH
= 
Moles of 
in 10 mL of diluted solution = 1/2 x moles of NaOH
= 
x 0.00333 = 0.00166 mol
Moles of in 25 mL of original solution
= moles of H2SO4 in 250 mL of diluted solution
= 
x 0.00166 = 0.0415 mol
Concentration of original solution = 
=
