Metabolism

Question 0

Krebs Cycle

Answer 0

Citric acid cycle; a set if 8 reactions arranged in a cycle in which free energy is recovered in the form of ATP.

Question 1

Electron Transport

Answer 1

The passing of electrons over a membrane aiding in a reaction to recover free energy for the synthesis of ATP.

Question 2

Beta Oxidation

Answer 2

A series if reactions in which fatty acids are broken down.

Question 3

Pyruvate

Answer 3

A by product of glycolysis.

Question 4

Glycolysis Pathway Calculation Formula

Answer 4

Glucose + 2Pi + 2ADP + 2NAD + 2 lactic acid + 2ATP + 2NAD

Question 5

ATP/CP Calculation Formula

Answer 5

ADP + CP —-Creatine Kinase— ATP + Creatine

Question 6

ATP Calculation Formula

Answer 6

ATP —-myosin ATPase—- ADP + Pi + Energy

Question 7

Oxidative Pathway

Answer 7

Oxygen combines w/lactic acid resynthesizing glycogen to produce energy aerobically.

Question 8

Glycolytic Pathway

Answer 8

Glucose is broken down to produce energy anaerobically

Question 9

ATP/CP Pathway

Answer 9

ATC/CP provide anaerobic sources of phosphate-bond energy. The energy liberated from hydrolysis (splitting) of CP rebonds ADP & Pi to form ATP.

Question 10

RQ Calculation Formula

Answer 10

RQ = volume of CO2 expired / volume of O2 utilized

Question 11

Respiratory Quotient

Answer 11

aka RQ - A method of determing the “fuel mix” being used giving us a way to measure the relative amounts of fats, carbohydrates, and proteins being burned for energy

Question 12

Thermogenic Effect

Answer 12

The heat liberated from a particular food is thus a measure not only of its energy content but also of its tendency to be burned as heat

Question 13

Calorie

Answer 13

A unit of heat

Question 14

Kilocalories

Answer 14

The amount of energy released when food is digested

Question 15

Basal Metabolic Rate

Answer 15

aka BMR - the minimum energy required to maintain the body’s life function @ rest. Usually expressed in calories per hour per square meter of the body surface

Question 16

Metabolic Set Point

Answer 16

The base rate if metabolism that your body seeks to maintain; results in your basal metabolic rate

Question 17

Catabolism

Answer 17

The breaking down in the body of complex chemical compounds into simple ones ( eg: amino acids to individual proteins)

Question 18

Anabolism

Answer 18

The building up in the body of complex chemical compounds from simpler compounds (eg: proteins from amino acids)

Question 19

Metabolism

Answer 19

The chemical processes occurring within a living cell or organism that are necessary for the maintenance of life. In metabolism some substances are broken down to yield energy for vital processes while other substances, necessary for life, are synthesized.

Question 20

Homeostasis

Answer 20

The automatic tendency to maintain a relatively constant internal environment.

Question 21

Training Effect

Answer 21

An increase in functional capacity of muscles & other bodily tissues as a result of increased stress (overload) placed upon them.
