Cellular Metabolism. Chapter 4. Cellular Metabolism. Cellular metabolism refers to all of the chemical processes that occur inside living cells. Energy. Energy can exist in two states: Kinetic energy – energy of motion. Potential energy – stored energy.
By Mia_JohnLecture 3 : How Matter is Organized. Chemistry is the science of the structure and interactions of matter. all living things consist of matter. Matter is anything that occupies space. mass is the amount of matter in any object. weight is the force of gravity acting on matter.
By kioraEnergy and Reactions. Honors Biology. Energy. Energy – ability to do work or cause a change Kinetic Energy energy of motion Ex: Heat, moving ball Potential Energy stored energy as a result of position or location Ex: Sitting ball ATP – adenosine tri phosphate
By milekWork, Energy & Power. Quick Review. We've discussed FORCES Magnitude – How hard is the “push” Direction – Which way does it act upon the object Applying a FORCE causes an object to accelerate (F=ma). m. F. F = m x a. (Units) lbs = lb-sec 2 /ft x ft/sec 2.
By cricketChapter 3. Matter & Energy. Matter. Matter is defined as anything that has mass and takes up space We can describe matter using Volume (may change under different conditions) Weight (changes with gravity) Mass (not affected by temperature, pressure, or gravity). Matter.
By bartoEQUILIBRIUM. REACTION RATES + ENERGY. Chemical energy of a substance = potential + kinetic energy. Kinetic energy = doing energy (mechanical) Potential energy = stored energy. What these energies result from. Attractions between electrons and protons Repulsion between nuclei

By brygid4.2 Energy is transferred when work is done. Tami Torres 2011. Some Helpful Definitions. Work ~ the use of force to move an object some distance. Joule ( jool ) ~ the standard unit of measure for work. One joule of work is done when a force of one Newton moves an object one meter.

By dyreCh. 7.1: Sunlight Powers Life. Vocabulary autotroph heterotroph cellular respiration plasma membrane photosynthesis producer consumer Objectives: Compare and contrast how autotrophs & heterotrophs obtain food. Explain how cellular respiration harvests the energy in food.
By virgoSection One Energy Energy : is the capacity to do some kind of work, such as moving an object. Examples: No matter how energy is defined, it is always involved when there is a change in matter. (Kinetic Energy: energy of motion) (Potential Energy: stored energy)
By koreneThermal Physics. What is the difference?. Temperature . . . Is that all? State . . . Solid, liquid or gas Movement of the molecules. What makes a hot body hot?. All matter is made up of tiny particles that are always in motion the kinetic-molecular theory.
By judithChapter 6 An Introduction To Metabolism. Metabolism/Bioenergetics. Metabolism : The totality of an organism’s chemical processes; managing the material and energy resources of the cell Catabolic pathways : degradative process such as cellular respiration; releases energy
By mediaTOPIC 5: Work, Energy & Power. WORK. Definition of Work: When a force causes a displacement of an object Components of the force need to be in the direction of the displacement. Net Work done by a Constant Net Force. Work = Force (F) x Displacement (x) W = Fx W = Fx = (Fcos θ)x
By dahliaEnergy. Kinetic energy = energy of motion. Energy. Potential energy = stored energy 1. energy of position due to gravity. Energy. Potential energy = stored energy 2. energy stored in chemical bonds. Law of Conservation of Energy. Energy can not be created or destroyed,
By lindsayHeat, Energy and Phases of Matter. Energy – ability to do work Work - force x distance Two types of energy Potential Energy – stored energy ex: stretched bow Kinetic Energy – energy in motion ex: swinging a bat. Energy. Joule - SI unit for measuring energy (J)
