Cell Respiration and Photosynthesis AP 2019

The purpose of cell respiration in a eukaryotic cell is to

• synthesize carbohydrates from CO2

• synthesize fats and proteins from CO2

• break down carbohydrates to provide energy for the cell in the form of ATP.

• provide oxygen to the cell

The process that produces the greatest amount of ATP during respiration is

• glycolysis

• Kreb's cycle aka citric acid cycle

• oxidative phosphorylation (chemiosmosis)

• lactic acid fermentation

Process by which glucose is split into pyruvate.

• glycolysis

• fermentation

• Kreb's or citric acid cycle

• Electron transport chain

Process by which H+ gradient is used to produce ATP

• chemiosmosis

• ETC--electron transport chain

• glycolysis

• Kreb's cycle

A process that makes a small amount of ATP and can produce lactic acid as a by-product.

• glycolysis

• fermentation

• ETC

• chemiosmosis

Carbon dioxide absorption is an appropriate indicator of photosynthesis because

• CO2 is needed to produce sugars in the Calvin cycle.

• CO2 is needed to complete the light reactions.

• plants produce oxygen gas by splitting CO2

• the energy in CO2 is used to produce ATP and NADPH

What is the purpose of photosynthesis?

• make glucose
• make ATP
• make light
• release carbon dioxide
