PPT-"Does biochemistry of living matter depends on environmental radiation?

Yeasts to human cells at the LNGS E Fratini on behalf of the Cosmic Silence Collaboration Underground Synergies with Astroparticle Physics MultiDisciplinary Studies. The US Environmental Protection Agency EPA is responsible for advising the government on radiation hazards and regulating certain sources of radioactivity in the environment This booklet provides basic facts about radiation science as well as inform Sections 37.4 – 37.5. Reminders. Today: In-class Quiz #6 addressing Chapter 37 and questions from prior quiz and test.. LAB B2-WNL: . Wave Nature of Light . due Friday @ 4pm.. Weekly Reflection #13 will be sent out after class today; due Tuesday evening after fall break.. Secs. 37.1-37.3. Reminders. Lab . D1-LFA: . Light from Atoms . due Friday @ 4 (this will be the last lab for the semester). In-class Quiz #6 Thursday, November 20???. Keep, reschedule, or delete . will address chapter 37 only. Bio “Life” . +. . Chemistry “Chemical Reactions”. . =. The study of chemical reactions in living things. . Why Biochemistry?. One characteristic of living things: life depends on . chemical reactions!. Radaition. vs Matter Dominance. Radiation vs Matter. Matter energy density and radiation energy density have difference dependence on expansion factor R:. Radiation density falls more rapidly than matter energy density.. Biochemistry. 1. What is Biochemistry?. Biochemistry = chemistry of life. . Biochemists use physical and chemical principles to explain biology at the molecular level.. Basic principles of biochemistry are common to all living organism. From Astronomy To Biomedicine. Light and Matter .  Spectroscopy. . Generalized interactions  Radiation. . Atomic physics. . Astrophysics. . Plasma physics. . Molecular physics. . Biophysics. Matter. Chemistry: study of matter. Matter: any thing that has mass . 3 phases: solid, liquid, gas. Both living organisms and non living things are made up of matter. Atom. The atom is the basic unit of matter. 1. What is Biochemistry?. Biochemistry = chemistry of life. . Biochemists use physical and chemical principles to explain biology at the molecular level.. Basic principles of biochemistry are common to all living organism. The time since the beginning of the universe is 1/H years or about 13.8 billion years.. The Big Bang started off immensely hot!. Radiation dominated the early universe.. Matter dominance occurs after radiation “cools” enough for matter to condense per the relationship E=mc. The Night Sky. The Milky Way. Stars (individual, binary, variable).

Cycling of matter within living systems. Example of living system: compost bin. Conservation of Matter. Matter of a closed system will remain constant over time. Matter is not created or destroyed but transformed into more complex forms.
