| MOST MECHANICAL WORK IS MEDIATED BY ___ PROTEINS FROM INRACELLULAR CYSTOSKELETON | MOTOR (IE. ACTIN MICROFILAMENTS;MYOSIN INTERMEDIATE FILAMENTS) |
| WHAT ARE THE 2 FORMS OF OF ENERGY? | KINETIC AND POTENTIAL |
| iN SCIENCE,ENERGY IS REFERRED TO STORED ENERGY IN ___ BONDS | CHEMICAL BONDS |
| ___ ENERGY REFERS TO MOTION | KINETIC |
| STORED ENERGY IS ___ ENERGY | POTENTIAL |
| A BALL ROLLING DOWN A HILL IS AN EXAMPLE OF ____ | KINETIC ENERGY |
| ELECTRIC CHARGE FLOWING THROUGH POWER LINES | KINETIC ENERGY |
| PERFUME MOLEC SPREADING THROUGH THE AIR | KINETIC ENERGY |
| A BALL POISED AT THE TOP OF THE HILL HAS __ ENERGY | POTENTIAL |
| A MOLEC ON THE HIGH SIDE OF CONCENTRATION GRADIENT STORES __ ENERGY BECAUSE IT CAN MOVE DOWN THE GRADIENT | POTENTIAL |
| IN CHEMICAL BONDS,____ ENERGY IS STORED IN THE POSITION OF THE e- | POTENTIAL |
| T/F KINETIC ENERGY AND POTENTIAL ENERGY HAVE THE ABILITY TO BECOME EACH OTHER | TRUE |
| WORK ALWAYS INVOLVES MOVEMENT,THEREFORE IS ALWAYS ASSOCIATED WITH __ ENERGY | KINETIC ENERGY |
| POTENTIAL ENERGY CAN BE USED TO PERFORM WORK,BUT WHAT MUST HAPPEN FIRST? | POTENTIAL ENERGY MUST CONVERT TO KINETIC ENERGY FIRST |
| WHAT HAPPENS TO ENERGY DURING THE CONVERSION OF POTENTIAL TO KINETIC ENERGY? | CERTAIN AMOUNT OF ENERGY LOST TO THE ENVIRONMENT AS HEAT |
| IS THE CONVERSION OF POTENTIAL TO KINETIC ENERGY 100% EFFICIENT? | NO |
| WHEN WORK IS USED TO PUSH A BALL UP A RAMP,WHAT IS HAPPENING TO THE KINETIC/POTENTIAL ENERGY? | MOVEMENT UP THE RAMP (KINETIC ENERGY) TRANSFORMS TO POTENTIAL ENERGY OF THE BALL'S POSITION |
| THE BALL SITTING ON TOP OF THE RAMP HAS ___ ENERGY AS THERE IS NO WORK BEING PERFORMED | POTENTIAL ENERGY |
| WHEN THE BALL ROLLS DOWN THE RAMP,___ ENERGY CONVERTS TO __ ENERGY | POTENTIAL (BALL ON TOP OF RAMP) TO KINETIC (BALL ROLLS DOWN THE RAMP) |
| AS THE BALL ROLLS DOWN,WHAT HAPPENS TO SOME OF THE KINETIC ENERGY? | IT IS LOST TO ENVIRONMENT AS HEAT DUE TO FRICTION BETWEEN BALL,RAMP,AND AIR |
| IN BIOLOGY, __ ENERGY IS CHANGED TO __ ENERGY WHEN CHEMICAL,TRANSPORT,AND MECHANICAL WORK IS NEEDED. | POTENTIAL ENERGY TO KINETIC ENERGY |
| WHAT 2 LAWS GOVERN THE TRANSFER OF ENERGY | 1ST AND 2ND LAWS OF THERMODYNAMICS |
| What is the law that states the total amt of energy in the universe stays constant;nothing enters or leaves,energy jUSt converts to another type | first law of thermodynamics or law of conservation of energy |
| T/F THE UNIVERSE IS CONSIDERED TO BE A CLOSED SYSTEM AND SO IS THE HUMAN BODY | FALSE;HUMAN BODY IS OPEN SYS / UNIVERSE IS A CLOSED SYSTEM |
| WHAT HAPPENS TO ENERGY THAT STAYS IN OUR BODIES | CHANGES FROM ONE TYPE TO ANOTHER [CHEMICAL,TRANSPORT,MECHANICAL WORK] |
| THE 2ND LAW OF THERMODYNAMICS STATES THAT NATURAL SPONTANEOUS PROCESSES MOVE FROM ___ TO ___. | ORDER (NONRANDOMNESS) TO RANDOMNESS/DISORDER/ENTROPHY |
| IN OPEN SYSTEM LIKE THE BODY,WHAT IS NEEDED TO CREATE AND MAINTAIN ORDER | INPUT OF ENERGY |
| WHY DOES DIORDER OR ENTROPHY BEGIN? | OPEN SYSTEMS LOSE ENERGY TO SURROUNDINGS W/OUT REGAINING IT |
