What is metabolism? All living things must have an unceasing supply of energy and matter. The transformation of this energy and matter within the body is called metabolism. Metabolism includes two different types: catabolism and anabolism. Catabolism is destructive metabolism. Typically‚ in catabolism‚ larger organic molecules are broken down into smaller constituents. This usually occurs with the release of energy. Anabolism is constructive metabolism. Typically‚ in anabolism‚ small precursor

As humans‚ we are the most dominant species in the world. We have the ability to walk upright‚ grasping thumbs‚ and large brains. This helps us to live and be successful on earth. But‚ these advantages we have didn’t happen overnight‚ they occurred during the hominine evolution. The skull‚ neck‚ spiral column‚ hip bones‚ and leg bones of the early hominine species changed shape in ways that later enabled species to walk upright. The evolution of dipedal‚ or two-footed‚ locomotion was very important

A. franciscana are known to live in high salinity lakes that are often basic (Biology 108 Lab Manual 2015). Furthermore‚ A. franciscana feed on photosynthetic phytoplankton which inhabit areas of light availability but are also more susceptible to predation in highly-lit areas (Biology 108 Lab Manual 2015). Also‚ A. franciscana can withstand a broad range of temperature except extreme values may affect survival (Biology 108 Lab Manual 2015). In this experiment‚ the habitat

enzyme-catalyzed reaction is called a substrate. The area of the enzyme that binds to the substrate is called the active site - where the action takes place. * Cofactors and coenzymes are small molecules or ions that help enzymes to act. HSC Biology Notes – Hugh Phillips Maintaining a Balance 1.Most organisms are active in a limited temperature range: Identify the role of enzymes in metabolism‚ describe their chemical composition and use a simple model to describe their specificity on substrates:
