Fatty foods ingested in the normal diet include	Cream and cheese
The only important digestible polysaccharide	Starch
An indigestible polysaccharide that aids elimination because it adds bulk to the diet is	Cellulose
protein- rich foods include ____and _____	Cheese/cream, Meat/fish
most examples of these nutrients, which are found largely in vegetables and fruits, are used as coenzymes	Vitamins
Include copper, iron, and sodium	Minerals
Which of the oxidative phases does not require oxygen	Glycolysis
Which phases do require oxygen	Krebs cycle and the electron
In which form is chemical energy transferred from the first two phases to the third phase	in the form of hydrogen atoms bearing high energy electrons
which of the phases produces the largest amount of ATP	the electron transport chain
Which phase combines energetic H atoms with molecular oxygen	The electron trasport chain
When you eat food that contains carbohydrates, you break down the carbohydrates into a monosaccharide called?	glucose
If you don’t use this monosaccharide, your body can store it in the liver in the form of	glycogen
Order the steps of aerobic (cellular) respiration. Which step does NOT produce ATP?	3 - Krebs Cycle 1 - Glycolysis 2 - Oxidation of Pyruvic acid (does NOT produce ATP) 4 - Electron Transport Chain (ETC)
Where in a cell does glycolysis occur?	In the cytosol
In glycolysis, a molecule of _________is split into two molecules of _________	glucose, pyruvic acid
How much energy (ATP) is needed to start the process of glycolysis?	(2) ATP (1 in step #1 and 1 in step #3)
How much energy is produced?	(4) ATP
What is the net gain in energy?	(2) ATP
Four high energy electrons are transferred to what carrier molecule?	(NADH) + (H+)
What is the purpose of forming (NADH) + (H+)?	to store energy for use in the electron transport chain
What is a disadvantage of glycolysis?	(2) molecules of ATP are used up in this process
In order to produce energy, cells start with glycolysis. If oxygen is NOT present after glycolysis, what process occurs next?	Fermentation (production of lactic acid)
If oxygen IS present after glycolysis, what process occurs next?	Oxidation of pyruvic acid
A process that does NOT require oxygen is known as:	anaerobic
Why is the oxidation of pyruvic acid necessary?	Because pyruvic acid cannot enter the Krebs Cycle, so it must be converted into something that can
The first reaction involved in the oxidation of pyruvic acid is ____where a _____ molecule is removed from pyruvic acid.	decarboxylation, carbon dioxide
The second reaction is the______of pyruvic acid and simultaneously the reduction of NAD (which becomes ______ to produce an acetyl group.	oxidation NAD (which becomes (NADH)+(H+) after it is reduced
The acetyl group combines with ______ to produce acetyl CoA.	coenzyme A
Where does the Krebs cycle occur in a cell?	In the matrix of the mitochondria
At the beginning of the Krebs cycle, the acetyl group combines with___ to produce	oxaloacetic acid, citric acid.
How many ATP molecules are formed with each “turn” of the cycle?	(1) ATP
How many NADH + H+ molecules are formed with each “turn” of the cycle?	(3)NADH +(H+)
How many FADH2 molecules are formed with each “turn” of the cycle?	(1) FADH2
Where do NADH + H+ and FADH2 come from? (Circle all that apply)	Glycolysis, Oxidation of pyruvic acid, Krebs cycle (all)
Where does the Electron Transport Chain (ETC) occur?	On the crista (folds) of the inner mitochondrial membrane
What is the source of electrons in the ETC?	they come from the reduced coenzymes (NADH + H+ and FADH2)
What molecule is the final acceptor of the electrons?	Oxygen
Electrons, the electron acceptor identified above, and H+ combine to form	H2O (water)
While electrons move along the electron carriers in the ETC, what happens to the H+?	they are pumped out of the matrix and into the intermembrane space
What charge builds up in the intermembrane space?	Positive charge
The enzyme_____uses the energy from the moving H+ to combine ADP and phosphate, forming high-energy	ATP synthase ATP
Every FADH2 molecule that enters the ETC will provide energy to create	(2) ATP.
Almost every NADH + H+ molecule that enters the ETC will provide energy to create	(3) ATP.
Why does FADH 2 produce fewer ATP molecules then HADH + H+ when it passes its electrons down the ETC?	because it carries lower energy electrons than (NADH)+(H+)
Oxaloacetic Acid->Acetyl Co A(goes in and back out as Co A)(+acetyl Group)->Citric Acid	Krebs Cycle
Glycolysis (event Glucose-> Pyruvic Acid)	[ATP(2)] [NADH+H+ (2)] [FADH2 (0)]
Oxidation of Pyruvic Acid(event Pyruvic Acid-> acetyl coenzyme A)	[ATP(0)] [NADH+H+(2)][FADH2 (0)]
Krebs Cycle (event:Acetyl group is completely used up	[ATP(2)] [(NADH)+(H+)(6)] [FADH2 (2)]
Rickets –	low vitamin D: Causes low Calcium absorption.Body can not absore Calcium so bones will get soft and brittle ( can result in Deformities
The key "fuel" used by body cells is_________	Glucose.
The cells break this fuel molecule apart piece by peice. the hydrogen removed is combinded with____ to form____, while its carbon leaves the body in the form of ____gas	oxygen water Carbon Dioxide
the importance of this process is that it provides_____,a form of energy that the cells can use to power all their activities	ATP
For Carbohydrates to be oxidized, or burned for energy, they must first be broken down to___	monosaccharides
When carbohydrates are unavailable to prime the metabolic pump, intermediate products of fat metabolism such as ___ and ___ accumulate in the blood, causing ___and low blood pH	acetoacetic acid, acetone ,ketosis
Amino acids that MUST be taken in the diet are called___amino acids.	essential
when amino acids are oxidized to form cellular energy, their amino groups are removed and liberated as ___	ammonia
in the liver , this is combined with carbon dioxide to form___ which is removed from the body by the kidneys	urea
The most used substance for producing the energy- rich ATP	Carbohydrates
Important in building myelin sheaths and cell membranes? The second most important food source for making cellular energy? Form insulating deposits around body organs and beneath the skin?	Fats / lipids
Tend to be conserved by cells? used to make the bulk of cell structure and functional substances such as enzymes	Amino acids
