Cellular Respiration - Please answer all the blank spaces.

My Pre-Test result is: My Post -Test result is. Record ALL your answers on this paper. is the name given to a series of biochemical reactions that uses to make 2. True or False: Cellular respiration occurs in both plants and animals. 3.is the first step in cellular respiration that begins releasing energy stored in glucose. It is the process that splits a molecule into molecules, and occurs in the 4. Cellular respiration in the presence of oxygen is known as The three metabolic pathways that take place are 5. After glycolysis, a 6 carbon molecule that is produced joins with a 4 carbon molecule to enter 86 first when

Explanation / Answer

1. Respiration uses glucose (Carbohydrate) to make energy (ATP)

2. True. Cellular respiration occurs in all the living organisms.

3. Glycolysis is the first step of the cellular respiration. It splits one glucose molecule into two pyruvate molecules. It occurs in the cytosol.

4. Cellular respiration that occurs in the presence of oxygen is known as aerobic respiration. It includes glycolysis, TCA cycle and electron transport chain

5. Citrate is the 6C molecule that is produced when Acetyl CoA joins with the Oxaloacetate. It is the first step of the TCA cycle. It occurs in the mitochondrial matrix. During Krebs cycle, Acetyl CoA breaks down to 2 CO2 molecules and produces high energy compounds GTP, NADH and FADH2.

6. NADH and FADH2 produced in TCA cycle enter the electron transport chain. They establish a proton gradient which is utilized by ATP synthase complex to produce ATP from ADP + Pi
