The molecular bonds between atoms are considered to be _____ in a food item, before you eat it.
Daniel [21]

Answer:

Chemical energy

<h2>Which form of energy does our food contain? </h2>

Yes, food serves as a basic source of the nutrients and energy needed to maintain and grow the body. Food contains what is referred to as "chemical energy" in terms of energy. This is nothing more than the bonds between the atoms that make up the specific food item, which the body may break down to release energy that it can use to create, repair, and ensure appropriate bodily function. This chemical energy is ultimately sunshine energy, which plants have the extraordinary capacity to use and store in the chemical compounds they produce, mostly in their leaves, using sunlight, water, and atmospheric carbon dioxide. Food does indeed contain energy, but that energy ultimately originates from the sun. Since people have known this for thousands of years, many civilizations revere the sun, along with water, air, and of course fire, as the source of life. For the body to function, energy is required by the muscles, brain, heart, and liver. The food we eat provides us with this energy. Our bodies break down the food we consume by combining it in the stomach with fluids (acids and enzymes). The carbohydrate (sugars and starches) in food is broken down into another form of sugar, termed glucose, during digestion in the stomach. The glucose is absorbed by the stomach and small intestines before being released into the circulation. Upon entering the bloodstream, glucose can either be utilized right away for energy or stored for later use. But in order to utilize or store glucose for energy, our systems need insulin. When insulin is absent, glucose remains in the circulation, which raises blood sugar levels. The glucose is burnt inside of your cells to create heat and adenosine triphosphate (ATP), a chemical that stores and releases energy as the cell requires. Either oxygen is present throughout the process of converting glucose into energy, or it is not. In the mitochondria, which are microscopic structures located in the gel-like fluid that fills every cell, glucose is transformed into energy using oxygen. This conversion results in waste products including water and carbon dioxide as well as energy (ATP, heat). Without oxygen, red blood cells convert glucose into energy because they lack mitochondria. ATP, heat, and lactic acid are produced as a result. Muscle cells also use glucose as a source of energy. Muscle cells are, well, double-jointed when it comes to converting glucose into energy. They can metabolize glucose with oxygen because they contain mitochondria. However, if the muscle cell's oxygen level plummets, the cells can simply convert glucose into energy on their own without it. When you have been working out so hard that you are physically out of breath, this is most likely to occur.

Kay [80]

Answer:

1. Part A: No

2. Part B: Yes

3: Part C : Yes

4: Part D : No

Explanation:

1) Part A: Facilitated diffusion of glucose into a muscle cell:

No; sodium ion co - transport is required for active transport of glucose but not for facilitated diffusion of glucose

2) Part B: Active transport of dietary phenylalanine across the intestinal mucosa:

Yes; co - transport of sodium ions drives the inward movement of amino acids and can only occur if sodium ions are actively pumped back out again.

3) Part C: Uptake of potassium ions by red blood cells:

Yes; uptake of potassium ions can occur only via a pump that couples the inward pumping of potassium ions to the outward pumping of sodium ions.

4) Part D: Active uptake of lactose by the bacteria in your intestine

No; active uptake of sugars and amino acids in bacteria is driven by a proton gradient.
