The primary way that animals, or more specifically, animal cells store glucose is in a compound known as glycogen. Glycogen is primarily stored by liver cells, but some is also stored in muscle cells for immediate use if needed. Glycogen molecules consist of many thousands of glucose molecules linked together by alpha acetal groups in a highly branched, very compact form.Continue Reading
Glucose is the primary fuel the body uses to create adenosine triphosphate, or ATP, the energy currency used by every cell on the planet. The brain, in particular, is almost totally reliant on a steady stream of glucose for operation. The muscles must also be ready to use energy at a much higher rate than digestion and circulation can provide. Glycogen is the body's way of keeping a quickly accessible form of energy on hand for these vital systems.
The body's capacity to store glycogen is limited. The liver and muscle cells can only store so much. When there is excess, glucose is not stored in glycogen, but is instead converted into fat, another form of compact energy storage, but one that takes longer to utilize than glycogen. Muscle cells use calories from digesting food or fats when energy demand is low, using their glycogen for more intense efforts.Learn more about Animal Reproduction
Understanding their breeding habits can help to control dangerous or poisonous animals if this information is used to disrupt breeding cycles or reduce fertility. Unsuccessful breeding strategies generally reduce populations of dangerous animals to manageable levels or even remove them from an area entirely.Full Answer >
Breeding videos provide information on how to identify and select animals with desirable genetic traits. They also detail the ideal breeding environment, diets and conditions needed for breeding. They show how to ensure that the mating procedure takes place to result in successful reproduction.Full Answer >
There are few observable traits distinguishing migrating animals from non-migratory species. Many birds, such as Arctic terns, mallards and bar-tailed godwits migrate across vast distances, while some of their close relatives remain in the same place all year. There are species of birds, fish, mammals, and even reptiles and amphibians that migrate each year.Full Answer >
The State University of New York states that animals reproduce by several sexual and asexual methods, with sexual reproduction, defined as the production of gametes with half of each parent's DNA and their union into diploid organisms, predominating. Sexual reproduction can be done externally, with eggs and sperm united outside an organism, or internally. Asexual reproduction takes a large number of forms, which vary between taxonomic groups.Full Answer >
