Which enzyme is activated by PKA that releases free fatty acids in adipocytes? |
Hormone-sensitive lipase. |
|
|
What is the substrate of hormone-sensitive lipase? |
Diacylglycerols. |
|
|
What is the function of perilipin and how is it regulated? |
Perilipin covers the lipid droplets in adipose tissue to prevent enzymes from breaking down the lipids. When perilipin is phosphorylated by PKA it floats away and no longer protects the lipid droplets, so lipolysis can occur. |
|
|
Which enzyme is activated after perilipin is phosphorylated? |
Adipose triglyceride lipase |
|
|
Which molecule is essential for transport of free fatty acids in blood? |
Albumin |
|
|
Which molecule is essential for transport of free fatty acids into mitochondria? |
Carnitine |
|
|
Which lipoprotein is the largest? |
Chylomicron
|
|
|
Which lipoprotein is the smallest? |
HDL |
|
|
Which lipoprotein contains the most triglycerides? |
Chylomicrons |
|
|
Which lipoprotein contains the most cholesterol? |
LDL |
|
|
Which lipoprotein contains the most protein? |
HDL |
|
|
Which enzyme is inhibited by steroids regarding pain killers? |
Steroids inhibit phospholipase A2. |
|
|
Which enzyme is inhibited by non-steroidal anti-inflammatory drugs (NSAIDs) regarding pain killers? |
