FLASHCARD QUESTION
Front
Back
Distributing energy within cells
Answer explanation
The primary function of the molecule, likely ATP, is distributing energy within cells. It provides the necessary energy for various cellular processes, making it essential for cell function.

FLASHCARD QUESTION
Front
Process in mitochondria producing large yield of ATP?
Back
Aerobic respiration
Answer explanation
Sophia is referring to aerobic respiration, which occurs in the mitochondria and produces a large yield of ATP. This process uses oxygen to efficiently convert glucose into energy, unlike the other options listed.

FLASHCARD QUESTION
Front
What is produced as a waste product during aerobic respiration?
Back
Carbon dioxide
Answer explanation
During aerobic respiration, glucose is broken down with oxygen to produce energy, and carbon dioxide is released as a waste product. Therefore, the correct answer is carbon dioxide.

FLASHCARD QUESTION
Front
Characteristic of anaerobic respiration
Back
Occurs in the cytoplasm
Answer explanation
Anaerobic respiration occurs in the cytoplasm, as it does not require oxygen. Unlike aerobic respiration, it produces less ATP and can generate byproducts like lactic acid or ethanol, not just carbon dioxide.

FLASHCARD QUESTION
Front
What happens to pyruvate in anaerobic respiration in humans?
Back
It is converted to lactate
Answer explanation
In anaerobic respiration, pyruvate is converted to lactate to regenerate NAD+, allowing glycolysis to continue. This process occurs when oxygen is scarce, such as during intense exercise.
6.
FLASHCARD QUESTION
Front
During which stage of cellular respiration is the majority of ATP produced?
Back
Electron transport chain
Answer explanation
The majority of ATP is produced during the electron transport chain, where electrons are transferred through protein complexes, driving ATP synthesis via oxidative phosphorylation. This stage generates the most ATP compared to glycolysis and the Krebs cycle.

FLASHCARD QUESTION
Front
Which organisms can perform anaerobic respiration?
Back
Plants, Humans, Yeast
Answer explanation
All of the listed organisms can perform anaerobic respiration. Yeast undergoes fermentation, humans can perform lactic acid fermentation, and some plants can also respire anaerobically under certain conditions.
