In an experiment, cells are treated with a drug that inhibits cytochrome C, how will this affect the cell.
Cytochrome C is an enzyme found on the inner mitochondrial membrane which binds cardiolipin and prevents the initiation of apoptosis (programmed cell death). If a cytochrome C is inhibited, cardiolipin will be released from the mitochondria and apoptosis will be initiated. The cell will die.
After a mastectomy, a patient complains of weakness when rotating her shoulder. What is the nerve most likely injured and the muscle it innervates?
The nerve most likely injured is the long throacic nerve and the muscle it innervates in the serratus anterior. This is may be accidentally cut at the lateral aspect of the mammary gland during surgery.
Find the slope of a line passing through the points (-2, -2) and (4, 4)
To find the slope of the line when given two point you must use the equation (Y2 - Y2) / (X2 - X1). So let Y2 = 4, Y1 = -2, X2 = 4, and X1 = -2. Now substitute the values for X and Y into the equation. (4 - (-2)) / (4 - (-2)) = (4 + 2) / (4 + 2) = 6/6 = 1
