Oxidation of a 24-carbon fatty acid would require _____ rounds of beta-oxidation and ______ rounds of the krebs cycle.
Anvisha [2.4K]

Oxidation of a 24-carbon fatty acid would require ELEVEN (11) rounds of beta-oxidation and TWELVE (12) rounds of the Krebs cycle. It is part of cellular respiration.

<h3>The Krebs cycle and cellular respiration</h3>

Cellular respiration is a group of chemical reactions by which aerobic cells can produce ATP by using energy from foods.

Cellular respiration has three parts: glycolysis, the Krebs cycle (also called the acid citric cycle) and oxidative phosphorylation.

During the Krebs cycle, hydrogen atoms or electrons pass through a series of hydrogen/electron carriers.

What volume of beaker contains exactly 2.23x10^-2 mol of nitrogen gas at STP?
nikklg [1K]

Answer:

V = 0.5 L

Explanation:

Given data:

Moles of nitrogen = 2.23×10⁻² mol (0.0223 mol)

Temperature = 273 K

Pressure = 1 atm

Volume = ?

Solution:

PV = nRT

V = nRT / P

V = 0.0223 mol × 0.0821 atm. mol⁻¹. L . k⁻¹ × 273 K / 1 atm

V = 0.5 L

Why doesn’t a convection current form when a liquid is heated at the top?
DaniilM [7]

If the heating is done on one small area on the top, there will be convection. If the heating is restricted to a small fraction of the heating area, then within that area the heating will go deeper than anywhere else on the surface. Then unheated area will have a shallower region of high temperature. Then some convection will occur in the deeper layers, causing some motion on top.

This happens quite a bit during welding. Convection is very significant in welding, even when the heating is from the top.
