Answer
Glycogen and starch are the storage forms of glucose in living things.
Solution
The correct answer is:
d. Glycogen and starch
**Explanation:**
- **Glycogen** is the storage form of glucose in animals, primarily found in the liver and muscle tissues.
- **Starch** is the storage form of glucose in plants, stored in various parts such as roots, tubers, and seeds.
The other options do not represent storage forms of glucose:
- a. Maltose and sucrose are disaccharides, not storage forms.
- b. Phytates and viscous fibers are not storage forms of glucose.
- c. Fibers and disaccharides are not storage forms; fibers are complex carbohydrates that are not stored as glucose.
Thus, glycogen and starch are the primary storage forms of glucose in living organisms.

Glycogen and starch are the main storage forms of glucose in living organisms. Glycogen, primarily found in animals and fungi, serves as a quick energy reserve, while starch is the primary storage form in plants, enabling them to store energy for later use. Both of these polysaccharides are composed of long chains of glucose units. In plants, starch exists in two forms: amylose, which is linear, and amylopectin, which is branched. This branching in amylopectin allows for rapid energy release when needed. In animals, glycogen is highly branched, making it efficient for quick mobilization of glucose during activities like exercise or fasting.
