Thirty-six.
18 oxygen atoms.
Energy cannot be created or destroyed, only transformed.
The energy available to do work in a system at constant temperature and pressure.
The chemical reactions taking place within a cell or organism.
Glucose and oxygen.
Various factors such as activation energy barriers or unfavorable conditions.
Mostly low energy bonds.
Glucose + 6 O2 → 6 CO2 + 6 H2O.
The coupling of endergonic reactions with exergonic reactions, which release energy.
12 hydrogen atoms.
It causes a net increase in entropy in the universe.
Glucose + 6 O2 → 6 CO2 + 6 H2O.
Glucose.
Glucose + 6 O2 → 6 CO2 + 6 H2O.
The amount of energy available to do work.
A negative change in free energy (–ΔG).
The set of life-sustaining chemical reactions in organisms.
From solar energy.
Exergonic reactions are chemical reactions that release energy, typically in the form of heat or light.
Some useful energy is lost as heat.
6 carbon atoms.
Carbon dioxide (CO2) and water.
Mostly high energy bonds.
The amount of entropy (disorder) in the universe is increasing.
Reactions that require an input of energy, indicated by a positive change in free energy (ΔG).
Glucose and oxygen.
Covalent bonds.
Answer the questions related to the lecture content.
There is a net increase in entropy.
6 CO2 and 6 H2O.
In any energy transfer, the total entropy of a closed system can only increase.
Carbon dioxide (CO2) and water.
Reactions that release energy.
The amount of energy in the universe is constant; energy can be transferred or transformed but not created or destroyed.
Endergonic reactions are chemical reactions that require an input of energy to proceed, resulting in products that have higher free energy than the reactants.
It goes from high free energy to low free energy.
Because it releases energy as it converts to more stable products (CO2 and H2O).
Reactions that require energy input to proceed.
