Accurate Answers
1. Lipolysis is _____ _.
the synthesis of new glucose molecules from pyruvate, lactate,
glycerol, or the amino acids alanine or glutamine
a set of biochemical reactions to prevent a toxic level of nitrogen
buildup in the body
a fuel in times of prolonged starvation or when patients suffer from
uncontrolled diabetes and cannot utilize most of the circulating
glucose
the breakdown of stored fat for release into the bloodstream and
used in cellular respiration
2. Describe how changes in metabolism affect the dietary needs of elderly
patients.
Elderly patients require more calories due to increased muscle mass.
As people age, their metabolic rate decreases, leading to lower
caloric needs.
Elderly patients need to consume more calories to maintain energy
levels.
Metabolism remains unchanged, so caloric intake should stay the
same.
3. Describe the role of phagocytosis in the immune response.
Phagocytosis plays a crucial role in the immune response by
allowing immune cells to engulf and destroy pathogens.
, Phagocytosis is involved in the transport of oxygen in the
bloodstream.
Phagocytosis regulates the temperature of the body.
Phagocytosis helps in the absorption of nutrients in the digestive
system.
4. Mitosis is a scientific term that, in layman's terms, means:
Atomic fusion.
Nuclear cell division (division of the cell nucleus).
Cellular disease.
Infection.
5. Describe how gross anatomy differs from microscopic anatomy.
Gross anatomy focuses on structures visible without a microscope,
while microscopic anatomy examines cells and tissues at a cellular
level.
Gross anatomy looks at living organisms, while microscopic anatomy
only studies dead specimens.
Gross anatomy studies the chemical processes in the body, while
microscopic anatomy studies the body's overall structure.
Gross anatomy is concerned with the functions of organs, while
microscopic anatomy is about their shapes.
6. What are the primary elements required for effective nerve conduction?
Chlorine and iron
Calcium and magnesium
Sodium and potassium
, Zinc and copper
7. What are the names of the body cavities that protect the nervous system?
Pelvic cavity and thoracic cavity
Abdominal cavity and cranial cavity
Cranial cavity and vertebral cavity
Thoracic cavity and abdominal cavity
8. If a cell's receptors for a specific nutrient are damaged, what impact would
this have on receptor-mediated endocytosis?
The cell would be unable to effectively internalize that nutrient.
The cell would enhance its receptor activity for other nutrients.
The cell would increase its production of that nutrient.
The cell would rely solely on passive diffusion for nutrient uptake.
9. Describe the significance of anabolic reactions in the context of cellular
metabolism.
Anabolic reactions are only important during cellular respiration and
not in other metabolic processes.
Anabolic reactions are crucial for growth and repair as they
synthesize complex molecules necessary for cell structure and
function.
Anabolic reactions are irrelevant to cellular functions and only occur
in specific tissues.
Anabolic reactions primarily focus on energy release and do not
contribute to cell growth.
, 10. The main function of cellular respiration is the
conversion of energy stored in the chemical bonds of glucose to an
energy form that the cell can use.
conversion of kinetic to potential energy.
recovery of NAD+ from NADPH.
elimination of excess glucose from the cell.
11. What is the primary purpose of inflammation in the context of tissue repair?
To initiate the healing process and prevent infection.
To promote cell division and growth.
To enhance nutrient absorption.
To reduce blood flow to the area.
12. What is the primary purpose of mitosis in cellular biology?
To synthesize proteins for the cell.
To divide a cell's nucleus and its genetic material.
To transport nutrients across the cell membrane.
To facilitate cellular respiration.
13. If a human red blood cell is placed in pure water, it will
lose water because of osmosis.
swell and burst.
gain water through active transport.
shrink in size.
