A: The corneal reflex is an involuntary closing of the eyelids when the cornea is touched by a foreign object. The function of this reflex is to protect the eye from damage. Absence of a corneal reflex may indicate damage to the fifth and seventh cranial nerves, which mediate the reflex.
Cellular respiration is the process by which the chemical energy of food molecules is released and partially captured in the form of ATP. Carbohydrates, fats, and proteins can all be used as fuels in cellular respiration, but glucose is most commonly used as an example to examine the reactions and pathways involved.
7th Grade Life Science . Photosynthesis & Cellular Respiration Study Guide . 1. What is the overall reaction (formula) for photosynthesis? 6CO. 2 + 6H. 2. O + sunlight C. 6. H. 12. O. 6 + 6O. 2. Carbon Dioxide and Water and sunlight yield Glucose and Oxygen . 2. How does this compare to the overall reaction for cellular respiration? Photosynthesis and Cellular Respiration are the reverse reactions of each other. 3. Where does the energy for photosynthesis come from? The sun . 4. What plant pigment is involved in photosynthesis? Chlorophyll . 5. How does your body get the energy it needs from the food you eat (what process allows cellular energy to be made)? Cellular Respiration . 6. In what organelle of a plant cell does photosynthesis take place? Chloroplast . 7. What are the products of photosynthesis? Glucose and Oxygen . 8. Write the equation for photosynthesis (CO2WS GO).
