Quiz - Physiology - Red Blood Cells

[Pedro Burrito]

From the Physiology Section of the PADI Dive Theory Exam:

What substance contained within the red blood cells aids in the transport of oxygen throughout the system?

a. Plasma

b. Cholesterol

c. Gammaglobulin

d. Hemoglobin​

I will post a daily question from my exams to help newer divers and to encourage more experienced divers to interact gracefully and helpfully with the newer divers.

Reminder - this is a post in the Basic Forum and it is a green zone. Please be nice and on topic.

Thank you for your patience while we try to give people something to discuss other than Covid-19 and/or Politics. I will post the answer covered by the spoiler tag later today.

I believe there is one family of vertebrates that does not use this molecule to transport oxygen. There are a number of invertebrates that use an alternative molecule to carry oxygen. Many of these live in the sea

Thank you for that. Very interesting how conserved hemoglobin is throughout the vertebrate animal Kingdom. I thought surely there was more than one family.
