What is metabolism? - Answers the biochemical reactions that occur in the body that are
necessary to maintain life
what is nutriton - Answers the process of providing or obtaining the food necessary to maintain
health and growth of the body
What are the 3 main functions of nutrients? - Answers provide energy, regulate body processes
and maintain cells and tissues
What are the 6 main classes of nutrinets? - Answers water, carbs, lipids, proteins, minerals, and
vitamins
What nutrients are able to provide fuel? - Answers carbs, protein, lipids (glucose main source of
energy)
simple sugars - Answers monosaccharides and disaccharides
complex carbohydrates - Answers Polysaccarides; starches found in grains, potatoes, and
vegetables
Erthrocytes and neurons connot metablize fats or amino acids to provide ATP so they require
______? - Answers glucose
What vitmains are water soluble? - Answers Vitamin B and C
What vitamins are fat soluble? - Answers Vitamins A, D, E, K
Catabolism - Answers Metabolic pathways that break down molecules, releasing energy.
Anabolism - Answers Metabolic pathways that construct molecules, requiring energy.
Anabolic pathway - Answers small molecules are assembled into large ones and energy is
required
Catabolic pathway - Answers large molecules are broken down into small ones. Energy is
released.
What is involved in catabolism? - Answers glycolysis, kerbs cycle, electron transport chain
What is involved in anabolism? - Answers protein synthesis, phospholipid synthesis, and
glycogen synthesis.
ATP structure and function - Answers Structure: Adenine, ribose sugar, and triphosphate group
Function: energy currency of the cell
, ATPase - Answers enzyme that hydrolyzes ATP to ADP
ATP synthase - Answers Large protein that uses energy from H+ ions to bind ADP and a
phosphate group together to produce ATP
What are enzymes? - Answers globular proteins that act as biological catalysts; increase the
rate of reaction and reduce the activiation energy
Apoenzyme - Answers catalytically inactive protein
Small portion of ATP is generated by: ________ that occurs in the cytoplasm and ______ and does
not require _______? - Answers Substrate level phosphorylation, cytoplasm and mitochondria,
oxygen not required
The majority of ATP is generated by: _________ __________ that occurs at the _________
___________ _______ and requires ______ - Answers oxidative phosphorylation, electron transport
chain, oxygen
Oxidation reducation (redox reaction) - Answers loss of electrons
Reducation reactions - Answers gain electrons
What are the coenzymes in redox reactions? - Answers Nicotinamide adenine dinucleotide
(NAD+) and Flavin adenine dinucleotide (FAD).
What is NAD+? - Answers an electron carrier that. Important conveyer of hydrogen and electrons
for the cell and is essential for the continued production of energy ATP by the mitochondria.
What is FAD - Answers flavin adenine dinucleotide responsible for accepting high energy
electrons and carrying them ultimately to the electron transport chain where they are used to
synthesize ATP. COmes from riboflavin and two ATP molecules.
ATP molecules are created when a _________ _______ is joined to ________ molecule. Resulting in
phosphorylation - Answers phosphate group, ADP molecule
Two ways that ATP is produced? - Answers substrate level phosphorylation and oxidative
phosphorylation.
in the cytoplasm during glycolysis and in the mitochondrial matrix during the Krebs cycle
yielding 4 ATPs/GLucose - Answers substrate level phosphorylation
occurs at the electron transport chain on the inner membrane of the mitochondria yielding 32
