Maintaining a Balance 1. Most organism are active in a limited temperature range The role of Enzymes in metabolism‚ their chemical composition and specificity on substrates Role of enzymes * Enzymes are organic catalysts. They are protein molecules that increase the rate of the reactions in living organisms. * Without enzymes‚ metabolic reactions at body temperatures would be too slow to produce sufficient energy to maintain life * Intracellular enzymes are used in the cells

What Is a Forest Ecosystem? Forests are important ecosystems that provide environmental and economic benefits. Forest ecosystems are unique environments and are categorized based on the types and ages of trees‚ climate and soil. They impact the environment at scales ranging from local to regional‚ by influencing climate‚ nutrient dynamics and water movement. Forests are found all over the world‚ and they provide valuable economic and environmental services. Information About a Forest Ecosystem

Whereas there may be more than one way of classifying titles‚ here we classify them on the basis of their structure. Classified thus‚ titles fall into five categories: (i) indicative titles; (ii) informative or declarative titles; (iii) question titles; (iv) hanging titles; and (v) series titles‚ with main title and sub-title. Indicative titles Indicative titles state the subject of the study rather than its conclusion. Examples are: (1) Influence of stocking density and grazing management on

AP Biology Summer Assignment Chapter 50.1: An Introduction to Ecology and the Biosphere Ecology is the scientific study of how organisms interact with the environment. When studying Ecology scientists want to know‚ where organisms live‚ why they live there‚ and how many are there. Ecology and environmental biology both stem from Darwin’s interest and observations upon the distribution of organisms and how they adapted to their specific environment. Darwin concluded that the environment interacting

Photosynthesis in C3 plants and their adaptations to the Mediterranean Climate Abstract. Photosynthesis is the process that plants use to harness the energy of the sun through light and use it to create sugars. Photophosphorylation is the first step of photosynthesis and occurs in the chloroplast. Light is captured by light harvesting complexes. The light excites electrons which excite surronding electrons through resonance induction and excite special pairs of electrons. These electrons help pump
