Textbook Question
Chapter 1.6, Problem 2CS
Core Skill: Modeling This modeling challenge asks you to propose a model for the structure of a mitochondrion in the presence of a drug that decreases the surface area of the inner membrane.
Modeling Challenge: Let’s suppose a cell is exposed to a drug that decreases the surface area of the inner mitochondrial membrane, but has no effect on the outer mitochondrial membrane. Draw a model of the structure of the mitochondrion in the presence of this drug.

Exercise 5
Membrane receptors are proteins that are incorporated in the cytoplasmic membrane of a cell, allowing the
detection of specific molecules such as (hormones, growth factor) and triggering a cascade of biochemical
Synthesis of protein
reactions.
The adjacent schema represents the steps of
the synthesis of these membrane receptors.
1. Label the structures from a to f.
In order to study the biosynthesis and
secretion of this protein (membrane
receptors), a solution containing radioactive
amino acid was injected in the blood of an
animal. Samples of certain cells were taken
at regular intervals of time. The intensity of
radioactivity was measured in different
cellular organelles.
