What happens during the Krebs cycle?

2 answers:

7 0

Because for each glucose molecule there are two pyruvic acid molecules entering the system, two ATP molecules are formed. Also during the Krebs cycle, the two carbon atoms of acetyl-CoA are released, and each forms a carbon dioxide molecule.

Answer:

Kerb cycle is the pathway through which most of the cellular energy (required for various metabolic processes with in a cell) is produced in the form of energy molecule ATP, NADH and FADH2

Explanation:

In a kerb cycle following happens sequentially -

a) Oxaloacetate (4 carbon compound) receives acetyl group (2 carbon) from acetyl CoA to produce citrate.

b) Enzyme aconitase act on citrate to convert it into isocitrate who ich is further converted to alpha-ketogluterate thereby releasing one molecule of NADH and CO2

c) alpha-ketogluterate is further converted into succynl-CoA accompanied by release of one molecule of NADH and CO2

d) ATP id produced while succynl-CoA is converted to succinate which is further converted to fumerate along with reduction of FAD to FADH2

e) Fumerate is then converted to malate and eventually to oxaloacetate by release of NADH

In one Kerb cycle, the end products produced are

2 × CO2

1 × ATP

3 × NADH

3 H+

1 × FADH2

Answer:

True.

Explanation:

Earth rotation can be defined as the amount of time taken by planet earth to complete its spinning movement on its axis. This ultimately implies that, the rotation of earth refers to the time taken by earth to rotate once on its axis. One spinning movement of the earth on its axis takes approximately 24 hours to complete with respect to the sun.

Basically, the effect of the Earth spinning on its axis on winds and currents is that, global winds will move along a curved path and therefore cause ocean currents to curve.

As a result of the Earth's rotation on its axis, a phenomenon known as Coriolis effect arises.

Coriolis effect occurs when circulating winds are deflected to the left in the southern hemisphere and to the right in the northern hemisphere.

Hence, rather than have this air circulating in a straight pattern, it is deflected to the left of the southern hemisphere and to the right of the northern hemisphere, typically in a curved path or pattern.

In conclusion, we can say that the deflection of fluids due to the rotation of earth is the Coriolis effect.
