Any form of active transport, which can be defined as any movement of molecules against or independent of a concentration gradient. Examples include pumps and endocytosis
Evaporation.
Melting chocolate requires energy input because the solid chocolate is transitioning into a liquid state. The energy input breaks the molecular bonds holding the solid together, absorbing energy in the process.
The transition from a solid to a gas involves two steps: first, the solid must melt into a liquid, absorbing heat energy in the process; then, the liquid must vaporize into a gas, which also requires an input of heat energy.
The magnitude of the energy change in the process of Mg turning into Mg+ is the ionization energy, which is the amount of energy required to remove an electron from a neutral atom to form a singly charged ion (Mg+). This process is endothermic, meaning it requires energy input.
Sublimation is an endothermic process because it requires energy input to change a substance from a solid directly to a gas without passing through the liquid phase.
Photosynthesis requires energy input in the form of sunlight to convert carbon dioxide and water into glucose and oxygen.
Evaporation.
Yes, the process of bond breaking requires energy input, not release.
Melting chocolate requires energy input because the solid chocolate is transitioning into a liquid state. The energy input breaks the molecular bonds holding the solid together, absorbing energy in the process.
The process of breaking bonds is endothermic, meaning it requires energy input to break the bonds.
The breaking of covalent bonds requires the input of energy. This energy can come from various sources such as heat, light, or electricity.
Passive transport processes, such as simple diffusion and facilitated diffusion, do not require energy input from the cell. These processes rely on the movement of molecules along a concentration gradient, from an area of high concentration to low concentration.
Photosynthesis is not a spontaneous process because it requires energy input from sunlight to convert carbon dioxide and water into glucose and oxygen.
Energy release is to condensation as energy input is to vaporization. Vaporization requires energy input to happen, while condensation releases energy.
Active transport is an endergonic process, meaning it requires energy input to move molecules against their concentration gradient.
Melting requires energy input or absorption because liquid water has more energy than solid water.
