Which of the following occurs in the citric acid cycle?
a) electron carriers will get reduced
b) oxygen is converted into water
c) coenzyme a gets broken down to make nadh, fadh2, and a small amount of atp
d) energy from acetyl is used to make recuding power in the cytosol
e) the three carbons of pyruvate gets released as co2

A) Electron carriers will get reduced

Explanation:

The citric acid cycle includes a breakdown of acetyl CoA into carbon dioxide and water. The redox reactions that breakdown the acetyl CoA release electrons which are accepted by NAD+ and FAD+. These electron carriers are reduced into NADH and FADH2.  

One round of citric acid cycle forms a total of 3 NADH and one FADH2 during the breakdown of one molecule of acetyl CoA.  

White blood cells change their shape to reach a site of infection.

Explanation:

White blood cells (leukocytes) are part of the immune system and have are responsible for tracking and killing pathogens such as bacteria. An important way white blood cells eliminate pathogens is by 'eating' them (pahgocytosis).

White blood cells circulate in the blood stream, but are usually required at the site of infection inside tissues. For this to happen, the white blood cells have to migrate through the walls of small blood vessels and have to be able to find their way in tissues . This can only occur because the white blood cells are able to change shape .
