Energy Metabolism - an overview | ScienceDirect Topics
网页Energy metabolism is the process of generating energy (ATP) from nutrients and comprises a series of interconnected pathways that can function in the presence or absence of oxygen. From: Sports, Exercise, and Nutritional Genomics, 2019
The Role of Energy and Metabolism - Biology LibreTexts
网页All living organisms need energy to grow and reproduce, maintain their structures, and respond to their environments; metabolism is the set of the processes that makes energy available for cellular processes.
Human Metabolism, Energy, Nutrients | Learn Science at Scitable
网页Energy metabolism is the general process by which living cells acquire and use the energy needed to stay alive, to grow, and to reproduce.
4.1: Energy and Metabolism - Biology LibreTexts
网页2021年9月27日 · Energy is exchanged between them and their surroundings as they use energy from the sun to perform photosynthesis or consume energy-storing molecules and release energy to the environment by doing work and releasing heat.
4.1 Energy and Metabolism - Concepts of Biology - OpenStax
网页Metabolic Pathways. Consider the metabolism of sugar. This is a classic example of one of the many cellular processes that use and produce energy. Living things consume sugars as a major energy source, because sugar molecules have a great deal of energy stored within their bonds.
Cell energy metabolism: An update - PubMed
网页2020年11月1日 · Cell energy metabolism hence refers to metabolic pathways involved in ATP synthesis linked to NADH turnover. Two main pathways are thus involved in cell energy metabolism: glycolysis/fermentation and oxidative phosphorylation.
Metabolism: What It Is, How It Works and Disorders - Cleveland Clinic
网页2021年8月30日 · Metabolism refers to the chemical (metabolic) processes that take place as your body converts foods and drinks into energy. It’s a complex process that combines calories and oxygen to create and release energy.
6.3: Energy in Metabolism - Biology LibreTexts
网页2021年8月23日 · The currencies of energy are generally high-energy phosphate-containing molecules. ATP is the best known and most abundant, but GTP is also an important energy source (energy source for protein synthesis).
