UPDATED QUESTIONS AND CORRECT
ANSWERS
What is the most common type of fat? - CORRECT ANSWERS✅✅triglycerides
What is the first step in breaking down fats for energy? - CORRECT ANSWERS✅✅to
separate fatty acids from glycerol backbone by HYDROLYSIS
What is Beta Oxidation? - CORRECT ANSWERS✅✅breaking fatty acids down into 2-
carbon units (acetyl groups)
In fat catabolism, each acetyl group yields how many APT? - CORRECT ANSWERS✅✅1
ATP from Krebs cycle
17 ATP from ETC
You can not make pyruvate from... - CORRECT ANSWERS✅✅acetyl groups
It is impossible to turn fats into ... - CORRECT ANSWERS✅✅glucose
Fats can be metabolized for energy by.... - CORRECT ANSWERS✅✅aerobic respiration,
only!
Can fats be fermented? - CORRECT ANSWERS✅✅NO
What can our cells do with fats? - CORRECT ANSWERS✅✅- can use fats for energy (only
in presence of oxygen)
- extra fat (not used for energy) is stored in fat cells
When using fat for energy, animal cells produce: - CORRECT ANSWERS✅✅Carbon
dioxide and water
, Fatty acids can be broken into acetyl groups by: - CORRECT ANSWERS✅✅Beta-oxidation
True or false: fat can be turned into glucose in case of hypoglycemia. - CORRECT
ANSWERS✅✅False - fat can not be turned in to glucose, ever!
True or false: our bodies can use protein for fuel? - CORRECT ANSWERS✅✅FALSE -
proteins are utilized in hormones, receptors, transporters, antibodies, clotting factors, etc.
_________________ ____________________ are used to provided the body with amino
acids which are to be used as building blocks to make the body's own proteins. - CORRECT
ANSWERS✅✅Dietary proteins
Our body NEVER makes _________________ of any kind any more than necessary. -
CORRECT ANSWERS✅✅proteins
The first step in protein catabolism is... - CORRECT ANSWERS✅✅the breakdown of a
protein into an amino acid via hydrolysis.
deamination of amino acids - CORRECT ANSWERS✅✅results in turning an amino acid
into a ketoacid, which can turn into pyruvate or an acetyl group.
The process of deamination produces - CORRECT ANSWERS✅✅ammonia (NH3)
Summary of protein catabolism - CORRECT ANSWERS✅✅1.) Break down of protein into
amino acids via hydrolysis
2.) Remove the amino group of the amino acid via deamination (produces NH3)
3.) Some ketoacids can turn into pyruvate, (if the body is running low on glucose).
4.) Pyruvate can be put through Krebs cycle & ETC or turn into glucose via reverse
glycolysis.
Making glucose from amino acids is called.... - CORRECT ANSWERS✅✅gluconeogenesis
