Question

1. Which of the following accurately compares fatty acid synthesis and fatty acid oxidation?

		All of the statements are accurate comparisons.
		Both processes require oxidized electron carriers.
		Both processes occur in liver cells.
		Both processes produce NADH.

2. When an inhibitor binds to electron transport chain complex IV, what effect(s) is/are produced? Select ALL.

		decreased rate of citric acid cycle reactions
		decreased rate of O2 consumption
		blockage of electron transport
		increased rate of protons pumped into the IM space

3. After complete oxidation of a fatty acid, name the product that contains the fully oxidized form of carbon.

4. Select whether each general statement about hormones is true or false.


   select an answer   true   false   Hormones can bind directly to metabolic enzymes and activate them.

   select an answer   true   false   In the blood, hormones are present in large concentrations to ensure an adequate response to the signal.

   select an answer   true   false   Hormones can produce the same response in different target cells.

Answer 1

Answer 1- Both the process i.e, fatty acid synthesis and fatty acid oxidation occurs in liver cells

Answer 2- When an inhibitor binds to electron transport chain complex IV, blockage of electron transport takes place

Andwer 3- Product is Acetyl Co-A.

Answer 4-a-False,because it binds through the receptor.

4-b-False,because hormone is secreted by the glands in case of need.

4-c-False,some hormones produce different effects on binding with different receptor. Eg- Angiotensin II cause vasoconstriction on binding with AT I receptor, while on binding with AT II receptor,it produces vasodilation.
