As a Reactant Glucose and as a product ATP and Co2 is common in Anaerobic and Aerobic Respiration

Explanation:

The "molecular process" that breaks down glucose, produces waste products, and energy is called respiration. Respiration has two types. These are "Anaerobic and Aerobic respiration". Oxygen is needed for Aerobic respiration but in Anaerobic respiration there is no need of oxygen.

Carbon dioxide and water are the waste product which is extracted in the Aerobic respiration and Anaerobic respiration produced alcohol or lactic acid or some other product as a waste product.

What is the evolutionary advantage of an exoskeleton?

Scorpion4ik [409]

Answer: E. A B, and C only

Explanation:

An exoskeleton is a hard, rigid, protective external structure that supports and protects the body of the animal from the damage caused either by injury or by predator. It supports and protects the inner organs and structures, acts as a barrier against desiccation. These act as a point of attachment of the muscles which provides a structural framework to the body. The exoskeleton is waterproof hence, protects the organism from being affected by the external water. It can be seen in the form of shells or scales, nails, hooves and other structures.

At label ________, the cell is not hyperpolarized; however, repolarization is in progress, as the sodium channels are inactivate

azamat

Answer: C

Explanation:

When a neuron receives a stimulus, the sodium channels present in the membrane are opened, and therefore Na+ enters the cell in favour of the concentration gradient, so that the membrane potential changes to positive by means of ion exchange, producing depolarization. If this depolarization reaches a certain threshold value, an action potential is generated. The next step is the opening of the potassium channels and the inactivation of the sodium channels, so that the repolarization of the membrane takes place. The sodium channels, will return to the closed state in the hyperpolarization to continue in this state during all the rest potential achieving the action potential to return to -70 mV (repolarization).; until the arrival of a new action potential which produces the activation and opening of the sodium channels, repeating the cycle again and generating a new depolarizing action. This process is part of the synaptic transmission.

So, hyperpolarization is any change in the cell's membrane potential, which makes it more polarized. This means, hyperpolarization is an increase in the absolute value of the cell's membrane potential. Thus, changes in membrane voltage where the membrane potential is more distinctly positive or negative are hyperpolarizations.

During the repolarization period after an action potential, the membrane potential is more negative than when the cell is in "rest period". In the picture, this repolarization period is about 1-2 milliseconds. <u>So, repolarization is the time in which the membrane potential is hyperpolarized with respect to the resting potential.</u>

In the attached figure, part C indicates this repolarization period.

Prokaryotes that obtain energy from sunlight are called

Varvara68 [4.7K]

Prokaryotes taht obtain energy from sunlight are called PHOTOTROPH. These prokaryotes use energy from the sun to synthesize organic compound for food and to carry out other metabolic processes. The energy synthesized from the sun is in form of ATP.

What is the main difference between aerobic respiration and anaerobic respiration?

garri49 [273]

The main difference between aerobic respiration and anaerobic respiration is that aerobic using oxygen in the reaction, while anaerobic does not.

Even though both aerobic and anaerobic respiration releases energy, but their reactants and other products are completely different.
For example in human, in aerobic respiration, oxygen and glucose reacts to give out carbon dioxide and water; while in anaerobic respiration, which usually happens during exercise when oxygen is not enough, the muscle cells uses only glucose to produce energy and lactic acid.

Therefore, the main difference is where aerobic uses oxygen, and anaerobic don’t.
