Pretend you are a teacher preparing a quiz for the text I will provide. 
            Each quiz question should follow the format below. 
            Ensure that you carefully recheck the questions and answers for accuracy. 
            The output should be a ready-to-use list of dictionaries for the Python eval function:

            d in oxidation-reduction 
reactions, as well as the oxidation of fatty acids, proteins, and other substances. 
B. The endoplasmic reticulum (ER) consists of the following: 
The smooth ER (SER) is involved in the synthesis of steroids, fats, and 
complex glycoproteins. It can also be used to detoxify harmful compounds. 
The rough endoplasmic reticulum (RER) contains ribosomes and produces 
proteins required for secretion from the cell or incorporation into the cell 
membrane. 
 
 
C. Ribosome 
The ribosome is composed of RNA and proteins and serves as the site for 
polypeptide synthesis. 
D. Golgi 
The Golgi apparatus temporarily stores proteins. 
E. Lysosomes 
Lysosomes contain digestive enzymes and enzyme precursors in an inactive 
form. 
Biochemistry studies cell components like amino acids, proteins, 
carbohydrates, and other organic substances, focusing on biological processes 
such as vitamins, hormones, and inorganic substances. It also examines the 
breakdown, biosynthesis, and energy processes of these components. Chemical 
reactions involving carbohydrates, lipids, and proteins, which are essential in 
food, are activated by enzymes and regulated by hormones secreted by endocrine 
glands. When these substances enter the digestive tract, they undergo several 
stages 
: 
i. 
Digestion 
 Food is broken down into simpler units that are easier to absorb and utilize. 
This process is facilitated by digestive enzymes found in the mouth, stomach, 
pancreas, and intestines. 
 
ii. 
Absorption 
These simple units produced from digestion are absorbed by the small 
intestine. The main goal of digestion and absorption is to transport these simple 
(primary) units from food to tissue cells through the bloodstream. However, some 
types of food do not require digestion and are absorbed as they are, such as water, 
glucose, vitamins, and minerals. 
 This process begins with the use of raw materials absorbed by the tissue 
cells, which then utilize these materials in one of the following two ways: 
 
1. Catabolic reactions (or breakdown reactions) refer to the process of 
breaking down substances, known as catabolism. 
2. Anabolic reactions (or synthesis reactions) involve the formation of new 
substances, known as anabolism or synthesis. 
The processes of catabolism and anabolism together form metabolism. 
Therefore, this term encompasses a series of reactions that occur within the 
tissue cells. 
 As a result of these reactions, new substances are produced, some of which 
are beneficial. Consequently, the body eliminates harmful or toxic substances 
through excretion or detoxification. 
Thus, it is clear that the products of metabolism return to the blood, from 
which they are filtered by the kidneys. The filtered contents reach the urinary 
tract, while the beneficial substances are reabsorbed.  
From the above, the importance of biochemistry in understanding the 
following becomes evident: 
- 
• Carbohydrates and their metabolism. 
• Lipids and their
