Biochemistry correct answers The study of life at the molecular level (common sets of reactions and principles that underlie all living organisms and the application of the principles of chemistry to explain biology) All living organisms have correct answers -the same building blocks (use them to create common Nucleic acids, proteins, polysaccharides, and lipids) -a common core of essential biochemical processes -great chemical complexity and microscopic organization -systems that allow them to use, extract, and transform energy from their environment -defined functions for each component that all have regulated interactions with each other (maintain homeostasis) -a response to stimuli due to mechanisms for sensing and responding to alterations in their surroundings -the ability to self replicate and self assemble -the ability to evolve over time Organisms are mostly made of: correct answers Carbon, oxygen, and hydrogen (98%) what accounts for much of the oxygen and hydrogen ? correct answers Water All organisms are ____-based (third most common element in living organisms) correct answers Carbon True or false: the abundance of elements in living organisms are similar to that of the earth's crust correct answers False Why is carbon considered versatile? correct answers Due to the number and variety of chemical bonds it can form What is the next best candidate for the chemical foundations of life? Why? correct answers Silicon. It also forms 4 covalent bonds and is highly abundant in the earth's crust Why is carbon the better candidate? correct answers Carbon-carbon bonds are stronger than silicon-silicon bonds (biomolevules), more energy is released on combustion of carbon bonds (fuel), combustion products of carbon (CO2) are soluble and remain active in the biosphere Changing one functional group can change the function of the molecule as a whole. What does this tell us about functional groups? correct answers Each functional group bring a unique property to the biomolecule ________ dictates function correct answers Structure Conformation correct answers Flexible spatial arrangements of atoms within a molecule (can be changed without breaking a bond)
