Explain the common similarity between prokaryotic and eukaryotic cells in at least 2
sentences. - ANSWERS-The fundamental similarity between prokaryotic and eukaryotic
cells is the presence of a plasma membrane. This structure separates life from non-life.
It acts as a barrier to the surrounding environment, but contains proteins that permit
select molecules to enter and exit the cell.
Would a scientist be more likely to find an element such as O in a biomolecule or W?
Explain which they would more likely find and give specific physical/chemical properties.
- ANSWERS-A scientists would be more likely to find an element such as O in a
biomolecule. Larger elements such as W tend to form ionic bonds, while smaller
elements like O tend to form more stable covalent bonds. Therefore, elements such as
O are more favored by biomolecules because they tend to form stronger bonds by
sharing electrons and forming significant overlap with other elements. As a result, these
stronger bonds require a substantial amount of energy to break them and allows the
bonds to withstand insults, such as thermal and mechanical stress.
Describe at least 3 properties of carbon the permit it to be the basis of life. - ANSWERS-
1. Carbon can form strong covalent bonds with a variety of different elements.
2. Carbon can also form double and triple bonds with other carbons atoms as well as
with other elements, such as nitrogen and oxygen.
3. Carbon can form long chains through bonding with other carbons to create long
polymers.
4. Carbon can also form cyclic structures, also referred to as ring compounds.
, What is the definition of inorganic chemistry? How does it different from organic
chemistry - ANSWERS-Inorganic chemistry is the study of minerals, metals, and other
non-carbon compounds.
Organic chemistry is the study of the chemical and physical properties of carbon.
Biochemists study the communication within and around organisms. According to the
module, what are 2 other aspects of living organisms that biochemists study? -
ANSWERS-1. The relationship between structure and function of biomolecules
2. Chemical reactions of organisms (metabolism)
3. Communication within and among organisms
In human cells, amino acids are degraded to ammonium NH4+ and carbon skeletons.
How is the nitrogen then further processed and excreted from these cell? - ANSWERS-
Nitrogen is processed separately from carbon and oxygen in the urea cycle. The urea
cycle is a 4-step cyclic process that converts NH4+ to urea, which can then be excreted
from the body. Once nitrogen has been removed from an amino acid through oxidative
deamination, NH4+ is converted to carbamoyl-phosphate by carbamoyl phosphate
synthetase 1 in the mitochondrial matrix. The nitrogen can then enter the urea cycle as
carbamoyl-phosphate in which it produces urea that contains two atoms of nitrogen in
the cytosol. The urea is then excreted.
What element is the basis for life? Describe at least 2 properties of this element that
permit it to serve as the basis for life. - ANSWERS-Carbon is described as the element
that is the basis for life due its ability to form:
- covalent bonds with different elements as well as form double and triple bonds with
other carbon atoms and elements, such as N and O
- structures known as polymers, which are long chains of carbon-carbon bonds.
- cyclic structures called cyclic compounds
Which types of molecules are most likely to be present in membranes? - ANSWERS-
Phospholipids, sphingolipids, cholesterol, and proteins are all most likely to be present
in membranes. According to the fluid mosaic model, these molecule work together to
form a bilayer membrane through association with each other.
