In which process CO2, is released as a by-product of oxidation-reduction reactions?
melamori03 [73]

Answer:

B) Krebs cycle (citric acid cycle)

Explanation:

Glycolysis breaks glucose into two pyruvate molecules. Pyruvate is decarboxylated into acetyl CoA and the reaction occurs in the matrix of mitochondria. In the mitochondrial matrix, acetyl CoA enters Kreb's cycle and is broken down into CO2 and H2O. For one molecule of acetyl CoA, two molecules of CO2 are released as a by-product. Therefore, out of three carbon atoms of pyruvate, two are released as CO2 during Kreb's cycle.

How are ocean ridges and trenches related? Describe their relationship in
True [87]

Terms that are asked to be used in the response are bolded;

     Ocean ridges and trenches are related in a few ways. One of the ways is being created from the movement of tectonic plates on the mantle when they diverge and converge. When tectonic plates diverge they "pull apart" and create trenches. When they converge they "push together" and create ridges, subduction happens here. The tectonic plates move on the mantle of magna from convection currents creating these different boundaries.

Have a nice day!

nalin [4]

Answer:

A hematocrit value of your blood would be greater than normal because of dehydration.

Explanation:

The hematocrit value is an indicator of the proportion of the solid components of blood (red blood cells) with respect to the liquid component (it means plasma). When you are severely dehydrated, the proportion of plasma diminish while the solid components remain the same. In consequence, the red blood cells concentration will be greater and the hematocrit value (solid components/plasma) will be higher than normal. This condition is reversible, if you drink enough water, your hematrocrit values will be normal again.
