When larger molecules are constructed from smaller molecules, this is known as
- A.
  
  Attraction
- B.
  
  Catabolism
- C.
  
  Anabolism
- D.
  
  Cataclysm
Correct Answer
C. Anabolism

Explanation
Anabolism is the correct answer because it refers to the process of building larger molecules from smaller molecules. This is the opposite of catabolism, which involves breaking down larger molecules into smaller ones. Cataclysm and attraction are unrelated to the process of constructing larger molecules from smaller ones.

Cellular metabolism is controlled by a specific kind of
- A.
  
  Muscle
- B.
  
  Protein
- C.
  
  Glucose
- D.
  
  Enzyme
Correct Answer
D. Enzyme

Explanation
Cellular metabolism refers to the chemical reactions that occur within a cell to maintain life. These reactions are regulated and controlled by specific molecules called enzymes. Enzymes act as catalysts, speeding up the rate of these reactions. In the context of cellular metabolism, enzymes play a crucial role in breaking down glucose, a sugar molecule, to produce energy. Therefore, the correct answer is enzyme, as it is the specific kind of protein that controls cellular metabolism.

Electrolytes that release hydrogen ions in water are called
- A.
  
  Salts
- B.
  
  Acids
- C.
  
  Catalyzed
- D.
  
  Synthesized
Correct Answer
B. Acids

Explanation
Acids are substances that release hydrogen ions (H+) when dissolved in water. This process is known as ionization. Therefore, electrolytes that release hydrogen ions in water are called acids. Acids are known for their sour taste, ability to react with metals, and ability to turn blue litmus paper red. They have a pH value less than 7 and can conduct electricity when dissolved in water.

When an excessive amount of fats are metabolized, it can be noted by
- A.
  
  Excessive thirst and nocturia
- B.
  
  Acetone in the breath and urine
- C.
  
  Constant hunger despite calorie intake
- D.
  
  Severe vomiting resulting in weight loss
Correct Answer
B. Acetone in the breath and urine

Explanation
When an excessive amount of fats are metabolized, the body produces ketones as a byproduct. Acetone is one type of ketone that can be detected in the breath and urine. Therefore, the presence of acetone in the breath and urine can indicate that the body is metabolizing fats at a high rate. This can be a sign of conditions such as diabetic ketoacidosis or a ketogenic diet.

Which of the following is an accurate definition of leukocytes?
- A.
  
  Protect against disease at the cellular level
- B.
  
  The body's only defense against infection
- C.
  
  Proliferate hemoglobin and carry oxygen to the body
- D.
  
  Carry amino acids to the kidneys for deamination and excretion
Correct Answer
A. Protect against disease at the cellular level

Explanation
Leukocytes, also known as white blood cells, are responsible for protecting the body against diseases at the cellular level. They play a crucial role in the immune system by identifying and destroying foreign substances, such as bacteria and viruses, that may cause harm to the body. Leukocytes are involved in various immune responses, including inflammation and antibody production, to ensure the body's defense against infection and disease.

The two main categories of leukocytes are
- A.
  
  Agranulocytes and basopjils
- B.
  
  Granulocytes and agranulocytes
- C.
  
  Neurtophils and granulocytes
- D.
  
  Monophils and lymphocytes
Correct Answer
B. Granulocytes and agranulocytes

Explanation
Granulocytes and agranulocytes are the two main categories of leukocytes. Granulocytes are characterized by the presence of granules in their cytoplasm, which contain various enzymes and proteins involved in immune responses. They are further divided into three subtypes: neutrophils, eosinophils, and basophils. Agranulocytes, on the other hand, do not have visible granules in their cytoplasm. They include monocytes and lymphocytes, which play important roles in immune responses such as antigen presentation and antibody production. Therefore, the correct answer is granulocytes and agranulocytes.

Neutrophils are also known as
- A.
  
  Polypeptides
- B.
  
  Polysaccharides
- C.
  
  Multigranulocytes
- D.
  
  Polymorphonuclear leukocytes
Correct Answer
D. PolymorpHonuclear leukocytes

Explanation
Neutrophils are a type of white blood cell that are characterized by their multi-lobed nucleus, hence the name "polymorphonuclear leukocytes". They are a crucial component of the immune system and play a key role in fighting off infections. Neutrophils are not polypeptides or polysaccharides, as these terms refer to different types of molecules. While neutrophils do contain granules, they are not specifically referred to as "multigranulocytes".

The life span of lymphocytes is
- A.
  
  12 hours
- B.
  
  2 weeks
- C.
  
  Years
- D.
  
  Days
Correct Answer
C. Years

Explanation
Lymphocytes are a type of white blood cells that play a crucial role in the immune system. They are responsible for recognizing and attacking foreign substances in the body. Unlike other blood cells, lymphocytes have a longer lifespan, ranging from months to years. This extended lifespan allows them to provide long-term protection against infections and diseases. Therefore, the answer "years" is correct as it accurately reflects the longer lifespan of lymphocytes compared to the other options provided.
