Ch 7 - Cellular Respiration

What is cellular respiration?

• the breakdown of glucose to release ATP

• the breakdown of glucose to release FADH

• the breakdown of glucose to release NADH

• the breakdown of glucose to release carbon

Glycolysis

• Requires oxygen

• Takes place in the cytoplasm

• Takes place in the mitochondria

• Requires a net input of ATP

• Is the same as fermentation

For each glucose input, the end molecule(s) of glycolysis is/are:

• 1 pyruvate

• 2 pyruvate

• 1 G3P molecule

• 2 G3P molecules

During glycolysis, NAD+ is _____ to NADH, which means it has ____ electrons.

• oxidized; lost

• oxidized; gained

• reduced; lost

• reduced; gained

During glycolysis, what is the net ATP production per glucose?

• 2 ATP

• 4 ATP

• 8 ATP

• There is no net production since ATP is required for the first part of glycolysis

By the end of glycolysis, pyruvate oxidation, and the Kreb's cycle, how many NADH molecules are produced per glucose?

• 2

• 4

• 6

• 10

Click on the two products of cellular respiration?

• H2O

• O2

• CO2

• glucose

What process of cellular respiration occurs in the cytoplasm?

• photosynthesis

• glycolysis

• Krebs cycle

• electron transport chain

Which is the correct chemical equation for aerobic cellular respiration?

• C6H12O6 + O2 ----> CO2 + H2O + ATP

• C6H12O6 + CO2 ----> O2 + H2O + ATP

• ATP + O2 -----> CO2 + H2O + C6H12O6

• C6H12O6 + H2O + O2 ------> CO2 + O2 + ATP

During the citric acid cycle (CAC):

• 3 FADH are reduced per cycle

• 3 NADH are reduced per cycle

• 4 ATP are produced per cycle

• glucose and other sugars are reduced while NADH is oxidized
