What is biochemistry??

77julia77 [94]

Biochemistry is the study of the actions of the main metabolic processes of living organisms, which are protein synthesis (DNA and RNA molecules, genetic codes and how they work, enzyme formation and function, etc), glycolysis (cellular respiration, aka the Krebs cycle/citric acid cycle to break down glucose molecules to release chemical energy and oxydative phosphorylation, the use of that chemical energy to form ATP molecules in which the chemical energy is put in a form the cell can use, and lipid chemistry (the study of the pathways in which fatty acids are formed into lipids and fat molecules and cholestrol formation and function).
Essentially, biochemistry covers the chemical reactions necessary for cellular and organism metabolism

explain how an element like carbon can be included in both the biotic and abiotic factorsof an ecosystem

Nadya [2.5K]

Well, the carbon cycle provides an example of matter cycling and energy flow in ecosystems. Photosynthesis, digestion of plant matter, respiration, and decomposition are important components of the carbon cycle, in which carbon is exchanged between the biosphere, atmosphere, oceans, and geosphere through chemical, physical, geological, and biological processes.

What happens when lakes are acidified?

Elena L [17]

The best answer is B - the fish die. Acid rain flows through soils. If the soil part of a watershed, aluminum is released from the soil and into the streams and lakes located in that watershed. This lowers the pH in the lake from between 6 and 8 (which is the normal pH in lakes and streams) to less than 5. Both increase of aluminum and lower pH are directly toxic to fish and they kill off fish populations
