Which of the following statements is/are true regarding the chemical reaction illustrated in the Figure?
It is a hydrolysis reaction.
It results in a peptide bond.
It joins two fatty acids together.
Which type of chemical bond involves the transfer of electrons from one atom to another, resulting in oppositely charged ions that are attracted to each other?
Covalent bond
Ionic bond
Hydrogen bond
Van der Waals interactions
Which of the following molecules is a carbohydrate?
Palmitic Acid
Collagen
Insulin
Lactose
Which of the following statements correctly describes the difference between saturated and unsaturated fats?
Saturated fats tend to be solid at room temperature; unsaturated fats are liquid at room temperature
Saturated fats are cannot pack together closely because of their bent structure; unsaturated fats can pack together because they are flat
Saturated fats come from plants and fish; unsaturated fats are from animals (except fish)
Saturated fats are considered “healthy” fats; unsaturated fats may contribute to cardiovascular disease
What do the error bars in the graph say about data?
The data for Group 1 has a lower mean value.
The data for Group 2 has a higher degree of variability.
The data for Group 1 has a higher degree of accuracy.
The data for Group 1 and 2 has the same degree of coefficient of variation.
The process by which protein conformation is lost or broken down is
dehydration synthesis
translation
denaturation
hydrolysis
The partial negative charge at one end of a water molecule is attracted to a partial positive charge of another water molecule. What is this type of attraction called?
a polar covalent bond
an ionic bond
a hydration shell
a hydrogen bond
Which two functional groups are always found in amino acids?
amine and sulfhydryl
hydroxyl and carboxyl
carboxyl and amine
phosphate group and nitrogenous base
Because of the unique properties of water associated with hydrogen bonding, water evaporates from pores on leaves of plants and draws water molecules in a continuous chain from the roots up through the vascular tissues of plants. Which of these groups of terms describes the process and properties of water that explain this?
adhesion, cohesion, and translocation
adhesion, cohesion, and transcription
cohesion, hybridization, and transpiration
cohesion, adhesion, and transpiration
Polymers of carbohydrates and proteins are all synthesized from monomers by which of the following processes?
the joining of monosaccharides
hydrolysis
dehydration synthesis
signal transduction
Monomers combine to form ________ through the process of ________.
polymers; hydrolysis
polymers; dehydration synthesis
monomers; hydrolysis
monomers; dehydration synthesis
How do phospholipids interact with water molecules?
Phospholipids dissolve in water.
The polar heads avoid water; the nonpolar tails attract water (because water is polar and opposites attract).
The polar heads interact with water; the nonpolar tails do not.
Phospholipids do not interact with water because water is polar and lipids are nonpolar.
Which of the following processes is primarily responsible for the movement of water from the roots to the leaves in plants?
Transpiration
Photosynthesis
Respiration
Glycolysis
In an experiment, a student adds a drop of iodine solution to a slice of potato. The potato turns blue-black. What does this indicate about the potato?
It contains glucose
It contains starch
It contains protein
It contains lipids
Which of the following best describes the role of enzymes in biological reactions?
They increase the activation energy required for the reaction
They decrease the activation energy required for the reaction
They are consumed in the reaction
They are produced as a byproduct of the reaction
