Correct Answer is C
Explanation
a. Pulls the edges of the wound together: Wound closure is a later stage of healing, not a primary function of inflammation.
b. Causes bleeding to clean out the wound: While some bleeding might occur initially, inflammation doesn't actively cause bleeding to clean the wound.
c. Cleans out debris and toxins from the wound: Inflammation is a natural response to injury or infection. It involves increased blood flow, redness, swelling, and heat. This process helps to deliver white blood cells and other immune factors to the area to fight infection and remove debris and damaged tissues, promoting healing.
d. Builds the scab to protect the wound: Scab formation is a result of dried blood and plasma, not a direct effect of inflammation.
Correct Answer is C
Explanation
a. Endoplasmic reticulum: The ER is involved in protein and lipid synthesis but is not the primary site of ATP synthesis.
b. Ribosome: Ribosomes are involved in protein synthesis but do not play a direct role in ATP production.
c. Mitochondria: Mitochondria are known as the powerhouses of the cell because they generate ATP through cellular respiration. Enzymes in the mitochondria facilitate the release of energy from nutrients, which is then used to recharge ATP molecules.
d. Lysosome: Lysosomes contain digestive enzymes that break down waste materials and cellular debris, but they do not produce ATP.
