Carbon compounds regulate the Earth's temperature, make up the food that sustains us, and provide energy that fuels our global economy. Most of Earth's carbon is stored in rocks and sediments. The rest is located in the ocean, atmosphere, and in living organisms. These are the reservoirs through which carbon cycles.
D- Biosphere
The part of the earth and its atmosphere in which living organisms exist or that is capable of supporting life
metabolism is (A) both catabolism and anabolism. Anabolism and Catabolism are two metabolic processes, or phrases.
catabolism is (B) reaction that breaks a larger molecules into smaller ones.
anabolism is (C) reaction that combines smaller molecules to make a large molecule.
Step 1: glucose is broken down into 2 molecules of pyruvate
Step 2: Completes breakdown of carbon dioxide, makes small amounts of ATP, provides electrons
Step 3: electron transport chain, chemiosmosis; energy from electrons-- produces 32 ATP
