polet [3.4K]

Because of different receptor types

Norepinephrine is also known as noradrenaline. It is released in the central nervous system which has a wide set of function in the body. This help in the activation of the flight or fight response by boosting the body to have an increased attention and reaction time. THis can increase the heart rate, dilate blood vessels and increased blood pressure however in other tissue function may vary due to the presence of various receptors that this neurotransmitter can activate.

Describe the flow of energy from a glucose molecule to ATP during respiration, and compare this to the flow of energy from gluco

svlad2 [7]

Answer:

Glycolysis is the first step of the cellular respiration in an organism which is metabolic pathway that is completed in the cytosol of the cell that leads to the converting glucose to the pyruvate in order to produce energy in form of ATP:

1. Glucose-6-phosphate is ---> fructose-6-phosphate

2. fructose-6-phosphate ---> fructose-1,6-biphosphate

3. fructose-1,6-biphosphate ---> glyceraldehyde-3-phosphate(GAP) and dihydroxyacetone phosphate (DHAP).

4. GAP is oxidised ----> 3-bisphosphoglycerate + NADH

5. 3-bisphosphoglycerate ----> 1,3-bisphophoglycerat

6. 1,3-bisphophoglycerate ----> 3-phosphoglycerate

7. 3-phosphoglycerate ----> 2-phosphoglycerate

8. 2-phosphoglycerate ----> phosphoenolpyruvate (PEP)

9. phosphoenolpyruvate to ADP ----> pyruvic acid + ATP

Formation of ATP occurs in both pathways or process that are respiration and fermentation. Fermentation is a catabolic pathway leads to the degradation of sugars (partial) that result in the gain of energy and this energy are absorbed in ATP. There are difference of the amount of energy or ATP produce in these process in respiration 38 ATP are produced whereas during fermentation only 2 ATP are produced.

Answer:

$0.972 J/g^{\circ}C$

Explanation:

When the sample of hot metal is placed inside the water, the metal gives off heat to the water: the temperature of the metal decreases while the temperature of the water increases, until the two reach an equilibrium temperature.

The heat given off by the metal is equal (in magnitude) to the heat absorbed by the water, so we can write:

$Q_m=Q_w\\m_m C_m (T_m-T_e) = m_w C_w (T_e-T_w)$

where:

$m_m=26.0 g$ is the mass of the metal

$C_m$ is the specific heat of the metal

$T_m=82.25^{\circ}C$ is the initial temperature of the metal

$T_e=28.34^{\circ}C$ is the equilibrium temperature

$m_w=75.0 g$ is the mass of the water

$C_w=4.186 J/g^{\circ}C$ is the specific heat of water

$T_w=24.00^{\circ}C$ is the initial temperature of the water

And solving for $C_m$ , we find the specific heat of the metal:

$C_m=\frac{m_w C_w (T_e-T_w)}{m_m(T_m-T_e)}=\frac{(75.0)(4.186)(28.34-24.00)}{(26.0)(82.25-28.34)}=0.972 J/g^{\circ}C$
