Biochemistry: concepts and connections (appling et al.)
Chapter 1: biochemistry and the language of chemistry
1) the water content in the human body is approximately:
A) 90%.
B) 80%.
C) 70%.
D) 60%.
E) 50%.
Ans>> c
Explanation:
About 70% of the human body’s mass is water. Water is vital for maintaining cell structure,
transporting nutrients, regulating temperature, and facilitating biochemical reactions. While
body water content varies slightly depending on age, sex, and fat content, 70% is the typical
average for a healthy adult.
2) the four most abundant chemical elements in living systems are:
A) hydrogen, oxygen, sulfur and phosphorus.
B) hydrogen, carbon, nitrogen and oxygen.
C) sodium, potassium, carbon and oxygen.
D) sodium, potassium, nitrogen and sulfur.
E) carbon, nitrogen, oxygen and potassium.
Ans>> b
Objective: 1.2
, 4
Explanation:
Living organisms are mainly composed of hydrogen (h), carbon (c), nitrogen (n), and oxygen (o).
These four elements form the backbone of biomolecules like proteins, carbohydrates, nucleic
acids, and lipids. They make up about 96% of the mass of most living cells.
3) nearly all proteins contain:
A) cobalt.
B) phosphorus.
C) selenium.
D) sulfur.
E) none of the above.
Ans>> d
Objective: 1.2 global lo: g7
Explanation:
Sulfur is found in amino acids such as cysteine and methionine, which are integral components
of most proteins. Sulfur-containing amino acids form disulfide bonds that stabilize protein
structure. Phosphorus is mainly found in nucleic acids, not proteins.
4) which of the following statements is false?
A) proteins can be structural components of cells.
B) proteins can transmit signals between cells.
C) proteins can transport molecules within cells and between cells.
D) proteins can be both hormones and hormone receptors.
E) proteins are the only biological polymer that can catalyze biochemical reactions.
Ans>> e
