Module 9-10 Flashcards
FADH2 results as one of the products of the citric acid cycle. (T/f)
True
Specifically in a cell, where does glycolysis occur?
Cytoplasm
The citric acid/ Krebs cycle breaks down carbohydrates into CO2. (T/f)
True
Specifically where in a cell does the citric acid/ Krebs cycle occur?
Mitochondrial matrix
The cell does not need ATP to survive. (T/f)
False
Glycolysis requires the investment of two______ in order to obtain a gross output of four _______
ATPs, ATPs
Where is carbon dioxide produced?
Mitochondrial matrix
Lymphatic tissue is composed of the following five components. List them.
Lymph nodes, lymphatic ducts, thymus, spleen, bone marrow
Natural killer cells are part of the specific immune system. (T/f)
False
A bacterium coated by antibodies is a signal that a macrophage should endocyrose (eat) it. (T/f)
True
Any cell can present an antigen on a class ii major histocompatibility complex (MHC) protein. (T/f)
False
How does lymph fluid return from the legs to the circulatory system?
Flexing the leg muscles pushes the lymphatic fluid up the lymph ducts (against gravity) with the help of one-way values in the duets that prevent back flow
Lymph nodes are a place where cells of the immune system accumulate and share information. (T/f)
True
Mast cells release histamine. (T/f)
True
There are times when the spleen can be considered to be the primary lymph node. (T/f)
True
Memory cells “remember” the antigen and make a faster and greater response the next time the antigen is encountered. (T/f)
True
Bone marrow is a site where mature immune cells are found. (T/f)
False
Having a fever of 100f can help you fight off infections. (T/f)
True
You should have your appendix removed whenever possible. (T/f)
False
When a B cell is shown an antigen on a class II major histocompatibility complex (MHC) protein it will go through _______ ________ and B cells subsequently can become ______ and/or _________
Blast transformation, plasma cells, memory cells
If a macrophage endocytoses (eats) an antigen it can digest it and present it on a _______ Major histocompatibility complex protein to a ______
Class II, helper T cell
B and T cells are called lymphocytes. (T/f)
True
Inflammation is caused by an increased blood supply due to ______ released by some cells of the immune system
Histamine
When immune cells mature and can recognize trans-membrane proteins indicating “self”, this is called _______
Tolerance
Does gravity have a role in some part of the lymphatic fluid flow back to the circulatory system?
Yes
In 1ml of blood, there are 1.5 million white blood cells. (T/F)
False
Red blood cells originate from the bone marrow (t/f)
True
Red blood cells are a part of the immune system. (T/f)
False
The humoral immune system involves cells in the immune system. (T/f)
True
In the lecture we discussed normal flora, this refers to:
Bacteria and fungi on the surface of the body that compete against the pathogens
A bacterium coated by antibodies is a signal that a macrophage should endocytose (eat) it. (T/f)
True
