Biology Unit 3 Cell Energy Review Sheet

Front

What is the difference between autotrophs and heterotrophs?

Back

Autotrophs obtain energy through photosynthesis, while heterotrophs obtain energy by consuming other organisms or organic matter.

Front

What happens when a phosphate group is added to ADP?

Back

It forms ATP.

Front

Define Cellular Respiration.

Back

Cellular Respiration is the process by which cells convert glucose and oxygen into carbon dioxide, water, and energy in the form of ATP.

Front

What builds up in muscles during prolonged exercise without conditioning?

Back

Lactic acid.

Front

What is the main difference between anaerobic and aerobic respiration?

Back

The main difference is the presence or absence of oxygen.

Front

What are the two main types of cellular respiration?

Back

Aerobic respiration and anaerobic respiration.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which autotrophs convert carbon dioxide and water into glucose and oxygen using sunlight.

Front

What is the role of ATP in cellular processes?

Back

ATP serves as the primary energy currency of the cell, providing energy for various biochemical reactions.

Front

What is lactic acid fermentation?

Back

Lactic acid fermentation is an anaerobic process that converts glucose into lactic acid and energy when oxygen is scarce.

Front

What is the equation for cellular respiration?

Back

C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP.
