bisc161: cellular respiration, carbon compounds, energy and redox
cellular respiration is broken down into five processes. we will use the flow charts and figures below to examine each reaction to determine what goes in and what comes out in terms of carbon compounds, redox reactions and energy.
directions: for each process, you will label where the process takes place, fill in the empty parts of the flow chart or figure and then make a record of what goes in and what goes out. under \carbon compounds\ make sure you write the number of carbons in each molecule. for all processes, keep track of the numbers of products produced in terms of a single glucose molecule. also, answer any other questions under each heading.

Explanation:

Step1: Identify carbon - compounds in glycolysis

One glucose (6 - carbon molecule) goes in. Two pyruvate (3 - carbon molecules each) come out.

Step2: Identify energy in glycolysis

2 ATP are used (energy in) and 4 ATP are produced (energy out), net 2 ATP gain. Also, 2 NAD+ are reduced to 2 NADH (energy - related redox product).

Step3: Identify redox reactions in glycolysis

Glucose is oxidized. NAD+ is reduced to NADH.

Answer:

Carbon Compounds In: Glucose (6 - carbon); Carbon Compounds Out: 2 Pyruvate (3 - carbon each); Energy In: 2 ATP; Energy Out: 4 ATP, 2 NADH; Redox Reactions - Oxidized In: Glucose; Oxidized Out: Pyruvate; Reduced In: NAD+; Reduced Out: NADH
