Phase 5

The Working Cell

Strength

• Ability to do work

• Types of one's

Kinetic energy – energy of movement

Potential energy – kept energy

Thermal energy - heat

Chemical energy -- potential strength of molecules

• Thermodynamics

– Study of energy

Oxidation-Reduction Reactions

• When an atom or molecule loses an electron, it truly is

said to be oxidized – method called oxidation

• When an atom or molecule benefits an electron, it is

said to be reduced – process referred to as reduction

• Oxidation and reduction often take place

together

• Lowered molecule has more energy than oxidized

molecule

• Energy associated with electron and length from

nucleus

First Law of Thermodynamics

• Energy cannot be produced or damaged

• It can only change from from one more

– Kinetic ↔ potential

• Total amount of energy remains a similar

Second Rules of Thermodynamics

• Energy conversions are not 100% useful

• Strength flows by high energy varieties to

varieties lower in strength

– This procedure is referred to as disorder

• Disorder in the galaxy is consistently

increasing

• Entropy is actually a measure of disorder in a program

• Entropy increases

Strength Gained

Energy Lost

With each alteration, there

is actually a one-way circulation of energy

back in the environment

Sun rays energy reaches

Earth. Makers secure

some and convert it to stored

kinds of energy. They will and all

different organisms convert

stored energy to forms that

can easily do cellular work.

Energy Lost

Electric power

• It requires energy to be able to chemical bonds

• Free energy – energy available to will work in any

program

• Endergonic reactions

– Products include more free energy than reactants

– Do not proceed spontaneously

– Require input of one's

• Exergonic reactions

– Products include less free energy than reactants

– Proceed spontaneously

– Release energy

Energy released Energy delivered

• Skin cells " earn” ATP in exergonic reactions

ribose

Electron Transfers

• Electrons will be transferred in virtually

just about every reaction that harnesses strength for use

inside the formation of ATP

• Coenzymes assist in electron exchanges

Electron Travel Systems

• Arrangement of enzymes, coenzymes, at

cellular membrane

• As one molecule is oxidized, next is definitely

reduced

• Function in aerobic respiration and

the natural photosynthesis

Concentration Gradient

• Means the number of elements or ions in

1 region differs from the others than the quantity in

one other region

• In the lack of other pushes, a element

moves via a region exactly where it is more

concentrated to 1 one where it's significantly less

concentrated -- " down” gradient

Durchmischung

• The internet movement of like molecules or ions

down a concentration gradient

• Although molecules collide at random, the

net movement can be away from the place with

the most collisions (down gradient)
