Why is glucose considered the most useful biological fuel?
Glucose is considered the most useful biological fuel because it is a primary source of energy for cells in the body. It is readily available from the breakdown of carbohydrates in our diet, and it can be efficiently converted into ATP through cellular respiration to power various cellular processes. Additionally, glucose is a versatile molecule that can be easily metabolized by a wide range of organisms for energy production.
What are the reactants of glycosis?
Glycolysis is the breakdown of glucose into pyruvate. There are ten reactions in glycolysis. The reactants are glucose, glucose 6-phosphate, fructose 6-phosphate, fructose 1,6 bisphosphate, dihydroxyacetone phosphate, glyceraldehyde 3-phosphate, 1, 3-bisphosphoglycerate, 3-phosphoglycerate, 2-phosphoglycerate, phosphoenolpyruvate and water.
Cells require glucose as a source of energy to carry out life processes. Large molecules like glucose cross the cell's plasma membrane by?
Large molecules like glucose cross the cell's plasma membrane primarily through facilitated diffusion, a process mediated by specific transport proteins known as glucose transporters. These proteins help transport glucose down its concentration gradient without using energy. In some cases, glucose can also enter cells via active transport, which requires energy to move glucose against its concentration gradient.
Cellular respiration converts energy from which form to which 2 forms?
During cellular respiration, the energy in glucose is converted, into 40 (38 net) ATP (Adenosine triphosphate) molecules, these are then used to carry out life's functions, such as homeostasis.
What happens to the energy stored in an autotroph when it is eaten by a heterotroph?
Autotrophs store energy in long chains of glucose molecules. These chains can be either starch or cellulose, depending on how the glucose are connected. When a heterotroph consumes the autotroph, it breaks down the cellulose or starch into its basic glucose components. The consumer either completely breaks down the glucose for energy, or it stores the molecules as fat or glycogen.

Where does the energy for life processes come from?
The energy for life processes comes from the food we eat. During the process of digestion, the body breaks down food into molecules that can be used as fuel to power various biological functions. These molecules, such as glucose, are then converted into energy through cellular respiration.

Why is respiration considered an exothermic reactionsExplain?
Energy is required to support life. Energy in our body is obtained from the food we eat. During digestion, large molecules of food are broken down into simpler substances such as glucose. Glucose combines with oxygen in the cells and provides energy. The special name of this combustion reaction is respiration. Since energy is released in the whole process, it is an exothermic process.

What are the examples of organic molecules?
Examples of organic molecules include carbohydrates (such as glucose), lipids (such as fats and oils), proteins (such as enzymes), and nucleic acids (such as DNA and RNA). Organic molecules are based on carbon atoms and are essential for life processes.
What is energy obtained by an organisim when it comsumes food?
Organisms obtain energy from food through the process of cellular respiration, where molecules like glucose are broken down to release energy stored in the form of ATP. This energy is used for various metabolic processes within the organism to sustain life and carry out activities.
What forms of energy are vital for life on earth?
The key forms of energy vital for life on Earth are solar energy, which powers photosynthesis in plants to produce food, and chemical energy, stored in the bonds of molecules like glucose for fuel. Both of these forms of energy are used by organisms to carry out their life processes and sustain growth and reproduction.

In some cases, glucose can also enter cells via active transport, which requires energy to move glucose against its concentration gradient.
Where does the energy captured in glucose truly come from?
The energy captured in glucose ultimately comes from the sun. During photosynthesis, plants absorb sunlight and convert it into chemical energy stored in glucose molecules. Organisms then utilize this stored energy in glucose through cellular respiration to fuel their life processes.
What is the process by which cells release energy in food to carry on life's processes?
Cells release energy from food through a series of chemical reactions known as cellular respiration. This process involves breaking down glucose molecules into ATP, which is then used as the cell's primary energy source to carry out various life processes. Oxygen is typically required for this process to occur efficiently.
State the significance of photosynthesis and cellular respiration to all life?
Photosynthesis is the main process on Earth that traps energy in food molecules. Cellular respiration breaks the bonds in the food molecules to put energy into a form that the cells can use directly. Three differences: 1. Photosynthesis requires water and carbon dioxide; respiration requires glucose and oxygen. 2. Photosynthesis produces oxygen and glucose; respiration produces carbon dioxide and water. 3. Photosynthesis builds glucose to store energy; respiration breaks glucose to release energy. 4. Photosynthesis happens in the chloroplasts; respiration happens in the mitochondria. 5. Only autotrophs carry on photosynthesis; all living things carry on respiration.
