As widely known, hormones control body metabolism. Although nutritional status and homones profile will influence lipogenesis rate, for simpliticy, insulin action along with glucose availability may be taken as master controlers in lipogenesis. These two factors signal cells by switching on and off AMPk-dependent processes, for exemple: low glucose and insulin levels will activate AMPk, which in turns inhbits energy-requiring processes and stimulates energy-releasing processes - in this case, lipogenesis will be switched off.

What else can I help you with?
How are fats synthesized in the body?
Fats are synthesized in the body through a process called lipogenesis, which occurs mainly in the liver. During lipogenesis, excess carbohydrates and proteins are converted into fatty acids and then combined with glycerol to form triglycerides, which are the main type of fat stored in the body. This process is regulated by enzymes and hormones, such as insulin, and is influenced by dietary factors.
What is the difference between tropic and nontropic hormones in terms of their functions and effects on the body?
Tropic hormones stimulate the release of other hormones from endocrine glands, while nontropic hormones directly affect target tissues or organs. Tropic hormones regulate hormone production, while nontropic hormones have direct physiological effects on the body.
Which of the following occurs in situations where more than one hormone produces the same effects at the target cell and their combined effects are amplified?
Synergism occurs when two or more hormones work together to produce an effect that is greater than the sum of their individual effects at the target cell. This amplification of the combined effects helps to enhance the overall response of the target cells to the hormones.
Where do endocrine secrete their hormones?
Endocrine glands secrete hormones directly into the bloodstream, where they are carried to target organs and tissues throughout the body. This allows the hormones to have widespread effects on various physiological processes.
Why do plants need hormones that have the opposite effects?
Plants use hormones with opposite effects to regulate growth processes in response to changing environmental conditions. For example, auxins promote cell elongation while cytokinins promote cell division, allowing plants to balance growth in different directions. This helps plants adapt to their surroundings and optimize their growth and development.
Is lipogenesis a postabsorptive state reaction?
No, lipogenesis is a state where excess energy is stored as fat for future use and typically occurs in the absorptive state following a meal when blood glucose and insulin levels are high. The postabsorptive state is characterized by the release of stored energy, such as glycogen and fatty acids, to fuel the body's energy needs when blood glucose levels drop.
What hormone stimulates lipogenesis?
Insulin is the hormone that stimulates lipogenesis, the process where the body converts excess carbohydrates into fat for storage. Insulin promotes the uptake of glucose from the blood into adipose tissue where it can be converted into fatty acids and stored as triglycerides.

Two hormones that have additive effects are called?
Synergistic hormones.
What does lipogenesis generally begin with?
Acetyl-CoA
What group of hormones exerts metabolic and cardiovascular effects during exercise?
thyroid hormones
What is the difference between tropic and nontropic hormones in terms of their functions and effects on the body?
Tropic hormones stimulate the release of other hormones from endocrine glands, while nontropic hormones directly affect target tissues or organs. Tropic hormones regulate hormone production, while nontropic hormones have direct physiological effects on the body.
What are two hormones that have additive effects call?
Hormones that have additive effects are often referred to as "synergistic hormones." When these hormones are released together, their combined effects amplify the overall response in the body, leading to a greater physiological impact than either hormone would produce alone. An example of this is the interaction between glucagon and epinephrine, both of which increase blood glucose levels.
List five different effects produced by these medullary hormones?
what are the medullary hormones You can't answer a question with a question...the medullary hormones (adrenal) they are referring to are epinephrine and norepinephrine.
How do hormones in food affect the growth of humans?
It is not clear if these hormones are bad for your health. Almost no research has been done on the health effects of these hormones in humans.It is difficult to separate the effects of added hormones from the mixture of natural hormones found in milk and meat. Buying organic may make people feel better, but there's little proof these products are safer.

What female sex hormones is most responsible for estrogenic effects?
Estradiol
