ACTUAL Exam Questions and CORRECT
Answers
Goal - CORRECT ANSWER - To gain a basic knowledge that will enable you to make
effective choices about your nutritional needs
Healthy Diet - CORRECT ANSWER - is one that provides the right amount of energy to
keep weight in the desirable range; the proper types and balance of carbohydrates, proteins, and
fats; plenty of water; and sufficient but not excessive amounts of essential vitamins and minerals.
Metabolism - CORRECT ANSWER - is the set of life-sustaining chemical transformations
within the cells of living organisms. These enzyme-catalyzed reactions allow organisms to grow
and reproduce, maintain their structures, and respond to their environments.
Anabolism - CORRECT ANSWER - uses energy to construct components of cells.
Reactions Require Energy (ATP)
Catabolism - CORRECT ANSWER - breaks down organic matter, for example, to harvest
energy. Release Energy (ATP)
Key Cellular Organelles - CORRECT ANSWER - Rough ER, Smooth ER, Nucleus,
Ribosomes, Mitochondrion
Cellular Respiration - CORRECT ANSWER - refers to the biochemical pathway by which
cells release energy from the chemical bonds of food molecules and provide that energy for the
essential processes of life.
Mark the statement(s) that are true:
A) Lipids can be synthesized in the endoplasmic reticulum
,B) The process of desperation to produce energy occurs in the mitochondria
C) Protein are made in the nucleus
D) All of the above - CORRECT ANSWER - A and B
Entropy and Disorder - CORRECT ANSWER - work is generally required to produce
order out of disorder, so energy must be used to produce a highly ordered state
Mitochondria - CORRECT ANSWER - participate in the chemical processes that transfer
energy from the chemical bonds of nutrient molecules to newly created adenosine triphosphate
(ATP) molecules
1) ATP, 2) Oxygen utilization, 3) Carbon dioxide formation
Oxidation - CORRECT ANSWER - is the loss of electrons or an increase in oxidation state
by a molecule, atom, or ion.
Reduction - CORRECT ANSWER - is the gain of electrons or a decrease in oxidation state
by a molecule, atom, or ion.
Enzyme - CORRECT ANSWER - biological catalysts that work by lowering the activation
energy for a reaction, thus dramatically increasing the rate of the reaction.
Which statement is false?
A) Going from an organized state to a disorganized state releases energy
B) Your body can't build new materials without taking other materials apart
C) Enzymes can cause biological reaction that otherwise could never occur
D) All of the above are true - CORRECT ANSWER -C
, Levels of organization of the human body - CORRECT ANSWER - chemical, cell, tissue,
organ, organ system, organism
Types of Tissues - CORRECT ANSWER - epithelial, connective, muscle, nervous
Corrolation - CORRECT ANSWER - statistical measure that indicates the extent to which
two or more variables fluctuate together. A positive correlation indicates the extent to which
those variables increase or decrease in parallel
Potential energy - CORRECT ANSWER - the energy stored within an object. This stored
energy is based on the state, arrangement, or position of the object.
1 kcal - CORRECT ANSWER - - increase of 1kg of water 1 C
- 1000 calories
What we eat - CORRECT ANSWER - Carbohydrates, Portein, Fat
How we use energy - CORRECT ANSWER - Basal metabolism, Thermic effect of food
(TEF), Physical activity, non exercise activity thermogenesis (NEAT)
Basal Metabolic RAte (BMR) - CORRECT ANSWER - The rate at which the body uses
energy while at rest to keep vital functions going
Surface Law - CORRECT ANSWER - The metabolic rate (heat production per unit time)
of an animal is proportional to their respective surface area
prediction of basal metabolic rate - CORRECT ANSWER - Metabolic rate is proportional
to weight (kg) to the 3/4 power. M=70.5W^(.75)
