Please understand that it is NEVER my intention to be disrespectful or rude to any of my students.  I have found through the years that it is often difficult to discern tone in texts and emails.  I know that I use caps in some of my emails or instructions but PLEASE do not interpret that to mean that I am yelling at you. I am not. I am just trying to emphasize important information.    If you have some sort of emergency please let me know and I can try to help you out. Also, if there is anything going on in your personal, financial, family, physical or spiritual life that is causing you issues that effect your performance in this class PLEASE feel free to talk to me about what is going on.  I try to maintain clear expectation and class rules but I am also a reasonable person and it is REALLY IMPORTANT to me personally that ALL of my students succeed.  If there is something that you think I should know about you and your particular situation I really hope that you feel comfortable talking to me about it.   If you understand this type yes in the blank.

Carbon monoxide is a colourless, odourless gas. It is produced whenever carbon-based fuels (coal, gas, wood, charcoal) burn in an atmosphere with a restricted oxygen supply. Thus, when carbon monoxide is inhaled, it enters the bloodstream, binds to hemoglobin, and crowds out the oxygen molecules, thus depriving the cells of the oxygen needed to maintain their vitality. Moreover, the iron atoms which are embedded in the hemoglobin molecule (and which normally bind oxygen to the hemoglobin) will hold onto any residual oxygen more tightly if carbon monoxide is present — resulting in even less oxygen being delivered to the cells and tissue. The cells die, and, for the brain, the cells cannot regenerate.It has been identified that carbon monoxide binds to hemoglobin at the same site as oxygen and forms carboxyhemoglobin. So based on your knowledge of competitive and non competitive inhibitors, determine the type of inhibition by carbon monoxide on hemoglobin :
