The first fuel Paul’s body uses is ________________________ from Paul’s last meal, which are stored in his _____________ & his ______________ (technically the bits in his BLOOD are used up before that even). The body turns them into ____________, which is burned in ____________. That fuel lasts Paul about ________________.

Answers

1. The first fuel Paul’s body uses is carbohydrate, which is generated from Paul’s last meal.

2. These carbohydrates are stored in his liver and muscles (technically, the bits in his blood are used up before that even).

3. The body turns the carbohydrates into glucose, which is burned in mitochondria during an aerobic cellular respiration.

4. That fuel lasts Paul about 3 miles, 40 minutes ([tex]\frac{2}{3} \;hours[/tex]).

A fuel can be defined as the resources that power the body of a living organism such as a human being. Also, the three (3) main types of fuel that power the human body include the following:

OxygenWaterFood

Fat is a nutritional element of food and it is beneficial to the body of a living organism because after the body exhausts its carbohydrates, it then uses its own fat as a fuel to power the body.

In this context, the first fuel Paul’s body uses is carbohydrate, which is generated from Paul’s last meal. These carbohydrates are stored in his liver and muscles (technically, the bits of carbohydrates in his blood are used up before the storage).

Furthermore, the body turns the carbohydrates into glucose, which is burned in mitochondria during an aerobic cellular respiration. Also, the fuel would only last Paul for a distance of about 3 miles, 40 minutes ([tex]\frac{2}{3} \;hours[/tex]).

What is the role of ATP in transport of materials

Answers

Answer:

Functions of ATP in cells

Explanation:

ATP plays a critical role in the transport of macromolecules such as proteins and lipids into and out of the cell. The hydrolysis of ATP provides the required energy for active transport mechanisms to carry such molecules across a concentration gradient.

Answer:

The role of ATP in the transport of materials :-

To move substances against a concentration or electrochemical gradient, the cell must utilize energy in the form of ATP during active transport. Primary active transport, which is directly dependent on ATP, moves ions across a membrane and creates a difference in charge across that membrane.

What does an alcoholic beverage contain that is a central nervous system depressant? 

Answers

Answer:

interferes with release of neural transmitter GABA

Explanation:

Alcohol is a central nervous system depressant, meaning it slows down brain functioning and neural activity. Alcohol does this by enhancing the effects of the neural transmitter GABA

depressants essentially "look" like the neural transmitter and so they go in and block the plasce in the brain between synapses, so when the body tries to release GABA, it appears as if it is already filled in, but in reality it is the alcohol that has filled it. once they start buidling up, they block enough that it impairs brain activity

Answer:

GABA

gamma-aminobutyric acid (GABA)

What flower has an ugly bud but a beautiful blossom?

Answers

Explanation:

Caladiums are tropical to sub-tropical plants grown mainly for their exquisite, colorful leaves. These foliage plants occasionally have a surprise up their metaphorical sleeve. Blooming on caladium plants isn’t common, but tubers planted in favorable locations tend to produce small flowers. These inflorescences aren’t as impactful as a rose or dahlia but have their own charm and, sometimes, a strong pleasant scent. There are several schools of thought on what to do with caladium flowers. While some growers believe pinching them off helps force energy to the tubers, others leave the small blooms with no ill effect on the plant.

What is not a type of arrythmia?

ventricular flutter
atrial flutter
atrial fibrillation
ventricular tachycardia

Answers

Given what we know about anatomy, we can confirm that atrial flutter is the option listed that may not be considered an arrhythmia.

What is an arrhythmia?An arrhythmia is classified as an irregular beating of the heart. What this means is that the heart will beat at rhythms different from the normal. A normal heartbeat can increase or decrease in speed, but as long as the beating follows a regular rhythm it is not considered an arrhythmiaThe atrial flutter can cause the heart to beat much faster than normal but maintains a regularity.

Therefore, since the atrial flutter causes the heart to beat very fast, but maintains a regularity to it, we can confirm that this is not a type of arrhythmia given that an arrhythmia is classified as an irregular beating of the heart.
