Flashcards in Nutrition And Metabolism Deck (26)
Inorganic ions released through the dissociation of electrolytes
Essential organic nutrients released to lipids and carbohydrates
Water - soluble vitamins
B1, B2, B3, B5, B6, B12, C, folic acid, biotin
Absorption of nutrients through food
All the chemical reactions that occur in the body
Chemicals produced in the body as a result of chemical reactions
Chemical reactions occurring within the cells, needed to maintain homeostasis as well as perform essential functions to maintain life.
Breakdown of organic molecules to release energy and synthesize ATP
Synthesis of new organic molecules, involves formation of chemical bonds
Sum of all anabolic and catabolic reactions at time of measurement
Basal metabolic rate
Minimum resting energy expenditures of an awake, alert person
Stores of amino acids, lipids, and simple sugars present in cells to be used for anabolism
Time during and shortly after eating when nutrients enter the blood from the GI tract
Period when GI tract is empty and body reserves are broken down to supply energy
Chemical reactions that involve the breakdown of glucose using O2
Chemical reactions that involve the breakdown of glucose without O2
Organic molecules needed for enzymatic reactions to occur
Substance level phosphorylation
High energy phosphate transferred directly from a substance to ADP to ATP
-Occurs during glycolysis and Kreb's cycle
Capturing energy to form ATP is coupled with movement of substances (protons)
-Occurs during electron transport chain
1. Glucose enters the cell through Glut-4 transporter
2. ATP+Enzyme are needed to convert glucose to glucose
3. A second ATP makes one long carbon chain with two phosphates on either side
4. Becomes 3 carbon chains
2nd ATP spent total
5. Add Pi to other side of each chain
Essential substances (Water, vitamins, ions, carbohydrates, lipids, proteins) obtained from the diet and absorbed from the digestive tract.
Why does lactic acid build up in tissues?
Due to inadequate amount of O2 being delivered to those tissue effected.
What is the goal of the TCA cycle?
To provide electrons and protons for the electron transport chain from carbon chains
What is the role of 02 in the electron transport chain?
To be the final acceptor , form water.
