Accepted Answer

Midsagittal plane

Answer

The midsagittal (median) plane passes through the midline of the body, dividing it into equal left and right halves.

Question 4

In cellular respiration, where does the Krebs cycle (citric acid cycle) occur?

Accepted Answer

Mitochondrial matrix

Answer

The Krebs cycle takes place in the mitochondrial matrix, where acetyl-CoA is oxidized to generate NADH, FADH2, and CO2.

Question 5
