Glucose metabolism begins with glycolysis and then proceeds to either the TCA (Krebs) cycle or fermentation. Glycolysis and fermentation are both anaerobic processes (they do not use oxygen) and use substrate level phosphorylation to produce ATP (e.g. energy), while the TCA cycle is aerobic (requires oxygen) and uses oxidative phosphorylation to produce ATP. Substrate level phosphorylation produces much less ATP than oxidative phosphorylation.
What else can I help you with?
Is the energy balance concept based primarily on the amount of sleep you get?
No, the energy balance concept is based on the relationship between energy intake (calories consumed) and energy expenditure (calories burned through metabolism and physical activity), regardless of sleep patterns. Sleep can affect energy balance indirectly by influencing appetite and metabolism, but it is not the primary focus of the concept.
Nuclear reactions produce huge amounts of energy by transfroming tiny amounts of matter?
Yes, nuclear reactions release a large amount of energy because a small amount of matter is converted into a significant amount of energy based on Einstein's famous equation, E=mc^2. This process is utilized in nuclear power plants and nuclear weapons.
What is the principle of nuclear reaction?
A nuclear reaction involves the changing of atomic nuclei through processes such as fusion or fission. These reactions release or absorb large amounts of energy. The principle behind nuclear reactions is based on the conversion of mass into energy, as described by Einstein's famous equation E=mc^2.
What form of energy is sunlight converted to?
Solar energy can be converted into electricity using photo-voltaic cells which are piezo-electric components and create a current when they are in light. Solar energy is also converted to usable heat using water based solar panels connected to a buildings radiators or hot water supply. Solar energy can also be converted into potential energy by certain wavelengths energising electrons in an atom to move to a different energy level. This is normally released back as light but will be a certain colour dependant on the wavelength absorbed. Solar energy can also be used to assist chemical reactions in plants using photosynthesis
How is it said that man gets energy from sun indirectly. How?
Through the process of photosynthesis, plants convert sunlight into chemical energy in the form of glucose. Humans then obtain this energy indirectly by consuming plant-based foods or animals that have consumed plants. This demonstrates the interconnected relationship between the sun, plants, and humans in the energy cycle.
The term metabolism is based on a greek word that means change. How is change related to metabolism?
You need energy for metabolism and energy is the ability to cause a change
Many carbon-based molecules are rearranged What molecule is made as a result of these reactions?
Glucose
During the Calvin cycle many carbon-based molecules are rearranged What molecule is made as a result of these reactions?
glucose
Is the energy balance concept based primarily on the amount of sleep you get?

Sleep can affect energy balance indirectly by influencing appetite and metabolism, but it is not the primary focus of the concept.
The series of chemical reactions in which a molecule of glucose is broken down is called?
The part of cellular respiration in which glucose is broken down is called the glycolysis. The chemical energy to produce ATP come from the breakdown of carbon based molecules into the smaller molecules.
How do plant and human get glucose molecules to use for energy?
plants synthesise the food in the form of glucose itself,which can be utilised by them.excess is stored as starch,which on hydrolysis ,again converts into glucose and utilised by plants.human get their food from plants as different nutrients which during digestion/metabolism convert to glucose via different pathways,by different enzymes,as per need and availability of nutrient in the body.
Why do some chemical reactions release heat while others absorb heat?
Chemical reactions release or absorb heat based on whether they release or require energy to break or form bonds between atoms. Reactions that release heat are exothermic, as they release energy, while reactions that absorb heat are endothermic, as they require energy input.
What is The concetration of glucose in intracellular fluid?
The concentration of glucose in intracellular fluid is typically around 1-10 mM (millimolar). This concentration can vary based on factors such as cellular metabolism, nutrient availability, and hormonal regulation.
What is the basal glucose level before physical exercise?
The basal glucose level before physical exercise typically ranges from 70 to 100 mg/dL in healthy individuals. This level can vary based on factors such as individual metabolism, diet, and time since the last meal. Maintaining an optimal glucose level is important for energy during exercise, as it helps fuel muscle activity and overall performance. Low basal glucose levels may lead to fatigue and decreased exercise capacity.
How do things react in science?
In science, reactions occur based on the interactions between different substances or forces. These reactions can result in changes such as chemical reactions, physical changes, or the release of energy. Understanding these reactions is a key aspect of scientific study and can help explain the behavior of matter and energy in the natural world.
What type of carbon based molecule is the first to be broken by your cells to provide a source of energy?
The first carbon-based molecule broken down by cells for energy production is glucose. Glucose is a simple sugar that is readily available from the breakdown of carbohydrates in our diet and is the primary source of energy for the body's cells.
This molecule stores energy and uses energy it is also found in sugars starches and fiber what is it?
ATP
