Question:

In an experiment, cells are treated with a drug that inhibits cytochrome C, how will this affect the cell.

Clarissa D.
Answer:

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.

Question:

Find the slope of a line passing through the points (-2, -2) and (4, 4)

Clarissa D.
Answer:

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
