The correct answer is
B. the thalamus→amygdala pathway
The neural pathway carries crude information about a threatening stimulus and activates a rapid instinctual alarm response is the thalamus→amygdala pathway
The thalamus→amygdala pathway is also known as the the path of fear. The thalamus transfers signal to other parts of the brain that causes the release of adrenaline and stress hormones.
Answer:
Hey, dont worry.
Explanation:
Climax communities are composed of a large variety of complex organisms. Climax communities are stable.
Answer:
Mitochondria- glycolysis
ATP synthase- converts ADP to ATP
Inner membrane- electron transport chain
Matrix- krebs cycle
Explanation:
The mitochondria forms the fundamental site for glycolysis. The glucose is broken down enzymatically to produce carbon dioxide, water and ATP. The krebs cycle is the first stage of aerobic respiration. It takes place in the mitochondrial matrix. ATP synthase is an enzyme that generates ATP during the process of cellular respiration. ATP synthase forms ATP from ADP and an inorganic phosphate (Pi) through oxidative phosphorylation. The mitochondrial inner membrane is the site of the electron transport chain, an important step in aerobic respiration. Energy obtained through the transfer of electrons down the ETC is used to pump protons from the matrix into the intermembrane space, creating an electrochemical proton gradient generating ATP.
Answer : The dissociation constant of the PFK‑inhibitor complex is, 5 µM
Explanation :
The expression for reversible competitive inhibition when apparent Km affected by addition of the inhibitor is:
![K_m_a=K_m[1+\frac{I}{K_i}]](https://tex.z-dn.net/?f=K_m_a%3DK_m%5B1%2B%5Cfrac%7BI%7D%7BK_i%7D%5D)
where,
= apparent value = 52 µM
= Michaelis–Menten constant = 40 µM
I = inhibitor concentration = 1.5 µM
= dissociation constant of the PFK‑inhibitor complex
Now put all the given values in the above formula, we get:
![52\mu M=40\mu M[1+\frac{1.5\mu M}{K_i}]](https://tex.z-dn.net/?f=52%5Cmu%20M%3D40%5Cmu%20M%5B1%2B%5Cfrac%7B1.5%5Cmu%20M%7D%7BK_i%7D%5D)
Therefore, the dissociation constant of the PFK‑inhibitor complex is, 5 µM
