Intro to photosynthesis (article) | Khan Academy
The ecological importance of photosynthesis. Photosynthetic organisms, including plants, algae, and some bacteria, play a key ecological role. They introduce chemical energy and fixed carbon into ecosystems by using light to synthesize sugars. Since these organisms produce their own food—that is, fix their own carbon—using light

Abstract. The energy substances (mainly carbohydrates and fats) are the basis and guarantee of life activity, especially the oxidative phosphorylation for energy supply. However, excessive absorption and accumulation of these substances can lead to metabolic diseases such as obesity, hyperlipidemia, diabetes, and cancers.

A very restrictive definition is as follows: Carbohydrates consist of carbon, hydrogen, and oxygen — with the hydrogen and oxygen occurring in a 2:1 ratio. There also must be at least three carbons. In other words, these are organic molecules that incorporate multiple water molecules and have at least three carbons.

Solution. Verified by Toppr. Correct option is C) Glycogen is a polysaccharide that serves as a form of stored energy in animals and fungi. Glycogen is made and stored in the cells of liver and muscles that are hydrated with the four parts of water. It acts as the secondary long-term energy storage.
Energy storage
Energy storage is the capture of energy produced at one time for use at a later time [1] to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential

In animals, glycogen and acylglycerols can be safely stored in large quantities and metabolised to produce energy and/or tissues. Much more energy can
Glucose & energy homeostasis: Lessons from animal studies
There are vegetative controls in the central nervous system, which keep the food intake and energy expenditure in check, so that energy reserves remain constant and thus the body weight as well. When the fat cells increase their fat storage, the adipose tissue releases leptin, the circulating satiety hormone, which signals the hypothalamus to regulate the
16.2: Carbohydrates
Starch is a storage form of energy in plants. It contains two polymers composed of glucose units: amylose (linear) and amylopectin (branched). Glycogen is a storage form of energy in animals. It is a branched polymer composed of glucose units. It is more
III. Carbohydrates, Structures and Types – A Guide to the Principles of Animal
The functions of polysaccharides include energy storage in plant cells (e.g., seed starch in cereal grains) and animal cells (e.g., glycogen) or structural support (plant fiber). Components of cell wall structure are also called nonstarch polysaccharides, or resistant starch, in animal nutrition, as they cannot be digested by animal enzymes but are

The present study analyzed the influence of horse age, substances used for marinating, and frozen storage on the quality of horse meat. It was conducted on the samples of the longest thoracic muscle, obtained from 12 carcasses of horses (aged 4–7 and 8–12 years). Among the analyzed samples, a higher fat content (p < 0.05) was found
Fat | Dietary, Animal & Plant Sources | Britannica
Fat, any substance of plant or animal origin that is nonvolatile, insoluble in water, and oily or greasy to the touch. Fats are usually solid at ordinary temperatures, such as 25 °C (77 °F), but they begin to liquefy at somewhat higher temperatures. Chemically, fats are identical to animal and.
