Cellular Respiration #biology #energy #cellularrespiration

the unit used to measure the heat energy required to increase the temperature of 1 kilogram of water by 1 degree Celsius.

the energy releasing chemical breakdown of food molecules, such as glucose, and the storage of potential energy in a form that cells can use to perform work

with oxygen

lacking oxygen

a quantity of heat equal to 1,000 calories. Used to measure the energy content in food- usually called a calorie.

a series of reactions that splits glucose into two molecules of pyruvate the first stage of cellular respiration

a coenzyme that can accept electrons during the redox reactions of cellular metabolism.

series of electron carrier molecules that shuttle electrons during a series of redox reactions that release energy used to make ATP

the chemical cycle that completes the metabolic breakdown of glucose molecules begun in glycolysis by oxidizing acetyl CoA to carbon dioxide.

glycolysis followed by the reduction of pyruvate to lactate, regenerating NAD+

glycolysis followed by the reduction of pyruvate to ethyl alcohol, regenerating NAD+ and releasing carbon dioxide

During glycolysis, each glucose molecule is broken down into two molecules of

If oxygen is present, the pyruvic acid of glycolysis will leave the cytoplasm and enter the _____________ reaction located in the mitochondria.

products of cellular respiration
