where does the energy for human metabolism com from?

Question

its for biology. and it kind of relates to photosynthesis. i think? help me. thanks :]

Answer 1

The human machine has three major sources of input energy: carbohydrates (bread, grains and simples sugars such as those in milk and fruit), protein (meat, legumes) and fats (too many kinds to name). When the body consumes one of these energy sources, the food molecules are broken down into smaller pieces using enzymes--doing so releases the stored energy in the food and provides small pieces from which to build more complex molecules.

Each food source has a specific role to play in metabolism. Carbohydrates are the dietary source of an important sugar called glucose. In fact, carbohydrates, such as the starch in potatoes, are simply very long chains of connected glucose molecules. Glucose is so important because it is the only source of fuel for the brain, red blood cells and several other tissues. Your brain uses about 120 grams of glucose per day. Any carbohydrate consumed in excess of what is needed for running the body's basic metabolic processes is converted to glycogen or fat for long term storage.

Answer 2

The body uses 3 main things from the food you eat for energy: 1) Glucose, 2) Fatty Acids, and 3) Amino Acids. The main energy comes from glucose, while fatty acids and amino acids are used more for cell formation.

Answer 3

The dispersal of ingested food into kinetic energy involves a long chain of events, too complex to describe here.

But at the cellular level, the mitochondria is what keeps the cellular fires going, converting food to energy.

Answer 4

Glucose for extra training, please ask this contained in the right talk board -- chemistry or biology, likely. do you comprehend that that's adversarial to Y/A regulations to submit a question contained in the incorrect talk board?

Answer 5

I thought it came from carbohydrates

Answer 6

I believe ATPs
