1.The correct answer is: It is produced in glycolysis and consumed in the citric acid cycle
Pyruvate is a molecule that connects metabolic processes of cellular respiration: glycolysis and Krebs (citric acid) cycle. Glycolysis is a process that occurs in the cytosol of the cell and in which several of enzymes catalyze the breakdown of glucose molecules. At the end of glycolysis, products are two pyruvate molecules and released energy (ATP).
After this step, in the matrix of mitochondria oxidation of pyruvate occurs. During this reaction, pyruvate is converted into a three-carbon molecule—acetyl CoA. Acetyl then acts as fuel for the citric acid cycle.
2.The correct answer is: electron transport chain
The amount of ATP produced per glucose is:
Glycolysis: 2 ATP
A process in which glucose is converted into two molecules of pyruvate, ATP is made, NAD+ is converted into NADH.
Krebs Cycle (citric acid cycle): 2 ATP
The acetyl CoA (made from pyruvate) goes through a cycle of reactions. ATP, NADH, FADH2 and CO2 is released.
Electron Transport Chain (oxidative phosphorylation): 28 ATP
Electrons from NADH and FADH2 move down the electron transport chain, protons are pumped out of the matrix, forming a gradient. Gradient of proton is used for the ATP synthesis.
Fermentation: 2 ATP
Breaking down carbohydrates (usually glucose) in the absence of oxygen.

Phrenology is the study of bumps on the head to predict a person's personality or behavior. It was developed in the late 1700s when a German doctor, Franz Gall, discovered that many criminals had particularly bumpy heads. Gall believed that the location of a bump determined characteristics such as kind manners, criminal instinct, or musical talent. Gall primarily studied criminals or hospital patients with oddly shaped heads, and he ignored any evidence that went against his findings. Today, with the use of technology and repeated studies, we know that many different parts of the brain affect a person's personality and behavior. Is phrenology an example of science or pseudoscience? Explain your answer.
