The energy from cellular respiration comes from food and air. The reactants first cellular respiration are oxygen and glucose. Glucose is a form of sugar and comes from food, and oxygen is found in air.
The main reactants or cellular respiration, as stated above, are oxygen and glucose.
During the first stage of cellular respiration, which takes place in the cytoplasm, a small amount of energy is produced when glucose is broken down into smaller particles.
Answer:
The esophagus.
Explanation:
Which is a long tube that connects the mouth to the stomach
Answer:
The body uses sugars from carbohydrates which supply the brain with glucose as the brain uses it as a "fuel source".
<h2>Why is glucose so important for the brain?</h2>
Quick answer: It takes a lot of energy to receive, interpret, and send signals via your neurons. Glucose is the simples sugar that can be used to make energy.
Cells require energy to carry out their typical everyday tasks. The simplest sugar that our cells can utilize for energy is glucose. Since your neurons are specialized cells, many additional cells are also present to support or protect them. All of the senses you can experience utilizing incoming neurons (from the body to the brain) are transmitted to and interpreted by the brain, including touch, pain, vibration, temperature, smell, sight, hearing, taste, and others. Signal reception and interpretation need energy. Additionally, your brain instructs your body to "do" things, which uses energy. Additionally, you spend a significant portion of your waking hours "thinking," which consumes energy. This explains why 20% of the glucose in your body is used by our teeny, tiny, little brains.

The cell membrane is semi permeable in nature, that is, it allows the passage of some substances while it disallows some substances. Small and non polar molecules pass quite easily through the cell membrane but large and polar molecules can not do this.
The substances which can easily pass through the cell membranes make use of passive transports such as diffusion and facilitated diffusion to enter the cells while substances which can not pass through the cell membranes on their own make use of active transport. Examples of active transport are endocytosis and ectocytosis,
