Answer:
Option A
Option D
Option F
Explanation:
During the process of continuous starvation for a long period of time, the primary source of energy in body is hepatic gluconeogenesis which is responsible for producing endogenous glucose. Also lipolysis takes place in the adipose tissue to release fatty acid which is then converted into ketone bodies through though mitochondrial β oxidation and ketogenesis. The liver communicates with extrahepatic tissues, including adipose tissue and skeletal muscle and deliver glucose and ketone bodies to muscle and other extrahepatic tissues as fuels.
Hence, option A, D and F are true.
Answer:
It accelerates the production of a second messenger.
Explanation:
Adenylyl cyclase is an enzyme capable of converting ATP molecules into cyclic adenosine monophosphate AMP (cAMP). The cAMP molecule is considered to be a second messenger that transfers the hormonal signal (i.e., epinephrine) inside the cell. Subsequently, cAMP activates molecular signaling events by binding and thus activating cAMP-dependent protein kinase A (PKA). Finally, this last protein (PKA) phosphorylates different proteins that control many diverse cellular processes.
Answer:
amino acids
Explanation:
(if you are confused, I recommend watching the videos from Khan Academy and The Amoeba Sisters.)
Answer:
B
Explanation:
Carbon is a versatile element and is found in many different chemical compounds, including those found in space. Carbon is versatile because it can form single, double, and triple bonds. It can also form chains, branched chains, and rings when connected to other carbon atoms.
