<h3><u>Answer;</u></h3>
d. a neuron recharges before it can fire again.
<h3><u>Explanation;</u></h3>
- <em><u>Refractory periods are a short phase in time following an action potential where another action potential cannot be generated. </u></em>
- <em><u>It is the period immediately following the transmission of an impulse in nerve or muscle, in which a neuron or muscle cell regains its ability to transmit another impulse. </u></em>
- There are two types of refractory period, that is the absolute refractory period and the relative refractory period. Absolute refractory period is the first part of a refractory period during which, the neuron will not fire again no matter how great the stimulation and this only lasts for a short time.
- Relative refractory period occurs when a stronger than usual stimulus is required to trigger the action potential before the neuron returns to resting state.
Answer:
3. All the species that live in a habitat.
Answer:
c. This statement is true because plants are able to convert sun energy into food energy and animals must get their energy from plants or other organisms that eat plants.
Explanation:
Green plants are autotrophs. They synthesize their food in the presence of sunlight, using carbon dioxide gas and water. Whereas animals are heterotrophs, they cannot make their food but use food prepared by green plants. Thus, plants are able to convert sun energy into food energy and animals must get their energy from plants or other organisms that eat plants. The statement is true.
6.25% of the energy contained in glucose is lost during the storage process. Glycolysis produces the molecules that are processed by the citric acid cycle.
- Each dietary glucose molecule produces 32 molecules of ATP when it enters the glycolysis and oxidation pathways directly.
- A net 2 ATP are produced during glycolysis for every gram of glucose. Per glucose, the citric acid cycle generates an extra 2 ATP. 28 ATP are produced by oxidative phosphorylation using the byproducts of glucose catabolism.
- 32 ATP molecules are created in this way. A cell could potentially store dietary glucose for later use, in the form of glycogen.
- One ATP must be used in this process in order to create glucose-1-phosphate (G1P).
- After then, G1P and UTP (uridine triphosphate) combine to form uridine-diphospho-glucose (UDP-glucose or UDPG). The UTP substrate, which is used in this phase, indirectly consumes ATP.
- Glycogen synthase can then utilise UDPG directly in the production of glycogen. This implies that each additional molecule added to a glycogen polymer uses up two ATP molecules.
- If two ATP molecules are used up during the storage of glucose as glycogen, then 2/32 or 6.25% of the energy contained in glucose is lost during the storage process.
