Trick question. Bacteria do not have cell walls. They barely have cell membranes. The second blank might be either chemosynthetic (break down chemicals for food) or photosynthetic (generate food from sunlight).
Answer:
The link reaction converts pyruvic acid to Acetyl-CoA.

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.

Explanation:
Organisms don’t have to only reproduce sexually or only reproduce asexually - some animals do both!
When conditions are good, such organisms will reproduce asexually because it is easier. For example, starfish (by fragmentation), slime molds, and water fleas/daphnia (by parthenogenesis) all reproduce asexually when there is plenty of food, minimal predators, and not too much crowding of individuals of the same species.
When conditions worsen (less food, too many individuals, etc), they may switch to sexual reproduction in order to add genetic variation to their population and ensure survival through difficult times.
