<span>The right answer is: *some of the energy that had been stored as chemical energy is lost as heat.
Breaking down an organic molecule into smaller ones is part metabolism of all the living organisms. It is called catabolism.
Catabolism is the set of reactions of molecular degradation of the organism considered. It is the opposite of anabolism, all synthesis reactions. Catabolism and anabolism are the two components of metabolism.Catabolism reactions are oxidations (or dehydrogenations) and they are thermodynamically favorable, that is they are exergonic (yielding chemical energy, producing energy). A part of this energy is used for biological activities, like moving, building or binding molecules together. The other part is released as heat. (You can take an example in the real life like running, the energy lets you moving and produces by the way heat)</span>
Answer:

- Light enters the eye through the cornea.
- Light travels to the macula within the retina.
- Rhodopsin absorbs light, and the Vitamin A changes shape.
- Vitamin A detaches from the rhodopsin, and some vitamin A is lost.
- Vitamin A from the bloodstream replenishes what is lost. The vitamin A returns to its original shape.
Explanation:
Retina is the part of the eye that contains photosensitive cells that capture light and produce the electrical signals that the brain perceives as images. These photosensitive cells are of two kinds:
Rods contain the photosensitive pigment, rhodopsin that is needed for vision at night or in dim light. Cones function in bright light.
Rhodopsin Bleaching:
Vision in bright or excessive light requires a process called rhodopsin bleaching which is the degradation of rhodopsin upon exposure to light. Upon contact with light, rhodopsin goes through structural changes characterized by the conversion of a pigment derived from Vitamin A, 11-<em>cis</em> retinal to all <em>trans</em> retinal. This chemical conversion initiates a photo-transduction reaction (reaction in which a photon of light is converted into electrical signals) that produces the electrical signals that travel to the brain via the optic nerve. The brain converts the electrical signals to images. This is followed by rhodopsin regeneration in the dark in which all <em>trans</em> retinal is converted back into 11 <em>cis</em> retinal.
I think the correct answer among the choices listed above is option C. The correct order of organizations of structures in living things from simplest to most complex should be c<span>ells as the most basic unit of life, Tissues, Organs and Organ Systems. Hope this answers the question.</span>
