QUARTER 2 (3rd PPT) Forms of Energy Laws of Energy Transformation Roles of ATP Flashcards
Is the study of the chemical substances and processes that occur in plants, animals, and microorganisms and of the changes they undergo during development and life.
Biochemistry
focuses on how living cells often produce, store or consume ATP.
understand how cells transfer energy in relation to processes like Respiration and Photosynthesis.
Bioenergetics
Is the process by which cells transform energy from one form to another.
Bioenergetics
2 types Potential Energy
Chemical Energy And Thermal Energy
Energy found in a substance
Chemical Energy
Stored chemical energy in a substance. (chemical bonds, nuclear bonds, electrostatic or intermolecular bonds)
Thermal Energy
Energy produce when atoms vibrate and produce heat
Thermal Energy
2 types of Kinetic Energy
Thermal Energy
Heat Energy
In biology, it refers to the study of energy transduction that occur in a living organisms.
Thermodynamics
the act of changing energy from one form to another
Transduction
To generate and maintain structure
To allow all kinds of movement
To maintain concentration and electrical gradients across membranes.
To maintain body temperature.
Function of Thermodynamics
It is made up of both the systems and surroundings.
Universe
It is the part of the universe on which you focus your attention.
Systems
Includes everything else in the universe
Surroundings
Energy is neither created nor destroyed, it can only change in form.
The quantity of energy of the universe always remain constant.
1st Law of Thermodynamics
By Rudolf Clausius
2nd Law of Thermodynamics
Also known as the Law of Entropy.
2nd Law of Thermodynamics
states that any spontaneously occurring process will always lead to an escalation in the entropy of the universe.
2nd Law of Thermodynamics
What is the significance of Entropy ?
The driving force for a spontaneous process is an increase in the entropy of the universe. A system and its surroundings always proceed to a state of maximum disorder or entropy. The total energy of the universe is constant, but the entropy is increasing. Energy conversions are not always 100% efficient. Some can be transduced in another form of energy.
Exergonic Reaction + Endergonic Reaction
Coupled Reaction
break chemical bonds of large reactants and produce smaller products
Exergonic Reaction
form chemical bonds of smaller reactants to produce larger products
Endergonic Reaction
