Bioenergetics Flashcards
Mention the 2 types of living beings:
- Autotrophic organisms
- Heterotrophic organisms
Explain Autotrophic organisms
- Example
- Source of energy
- Source of carbon
- Example: Photosynthetic bacteria and higher plants
- Source of energy: Solar energy 🌻
- Source of carbon: Atmospheric CO2 to form its molecules
Fotosintesis
Explain Heterotrophic organisms
- Example
- Source of energy
- Source of carbon
- Example: Humans 💁
- Source of energy and matter (carbon): Organic molecules (synthesized by autotrophic organisms)
Obtienen la energía a través de la digestión
What are the biomolecules ingested with food?
Are the supply (suministro) of matter and energy.
Of what matter is constituted?
Chemical elements (CHONP)
Of what energy is constituted?
Chemical bonds (enlaces químicos)
¿La degradación (de materia y energía) qué le va a permitir generar a los organismos heterotrofos?
Lo pueden usar en funciones biologicas
Energía metabolica
Es la unión de los elementos químicos (CHONP) –> nos dan materia JUNTO con los enlaces bioquímicos –> nos dan energía
Describes the transfer and utilization of energy 🔋 in biological systems.
Bioenergetics.
Bioenergetics:
Mention where the concept of FREE ENERGY comes:
Describes the transfer and utilization of energy 🔋 in biological systems.
It comes from THERMODYNAMIC
- What does Bioenergetics predicts?
- What does Kinetic measure predicts?
- If a process is possible
- How fast the reaction occurs
In bioenergetics we only care of:
The initial and final energy of reaction components.
Type of energy that tells us how predictable a reaction is to happen or not happen:
Free energy
Free energy:
It tells us how predictable a reaction is to happen or not happen.
What type of energy can be by agitation or by the power that these molecules already have (kinetic energy):
Thermal energy or heat
Thermal energy or heat:
It can be by agitation or by the power that these molecules already have (kinetic energy)
