List, in order, the events in visual perception that must occur for a person to see an object:
1. Potassium channels opens, allowing potassium ions to move out.
2. Some sodium channels open in the dendrite.
3. All ion channels close and the Na+/K+ exchange pump starts working.
4. Sodium ions diffuse toward a node of Ranvier.
5. Lights hit the retina.
6. The threshold level is reached.
7. Many sodium channels open in the axon membrane, allowing sodium ions to move in.

a "theory" a suggestion that is not 100 % accurate, or a figure. some people say its a theory because they of all the passed theory's about one subject. it depends sometimes theory might be accurate and sometimes they are.

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.

idk lol use google m8
