Aerobic Respiration

Front

Anabolism:

Back

Building complex molecules from simpler ones.

Answer explanation

Anabolism is the metabolic process that builds complex molecules from simpler ones, such as synthesizing proteins from amino acids. This distinguishes it from catabolism, which breaks down molecules.

Front

Steps of aerobic respiration

Back

Glycolysis -> Citric Acid Cycle -> Oxidative Phosphorylation

Answer explanation

The correct sequence of aerobic respiration is Glycolysis, followed by the Citric Acid Cycle, and finally Oxidative Phosphorylation. This pathway efficiently converts glucose into ATP.

Front

Reactants for cellular respiration:

Back

glucose + oxygen

Answer explanation

The reactants for cellular respiration are glucose and oxygen. Glucose provides the energy source, while oxygen is essential for the process of aerobic respiration, allowing cells to produce ATP efficiently.

Front

Final step of glycolysis produces ATP via:

Back

Substrate Level Phosphorylation

Answer explanation

In the final step of glycolysis, ATP is produced through Substrate Level Phosphorylation, where a phosphate group is directly transferred to ADP from a phosphorylated intermediate, rather than through oxidative phosphorylation.

Front

After NAD+ receives electrons, it changes to:

Back

NADH

Answer explanation

After NAD+ receives electrons, it is reduced to NADH. This process is crucial in cellular respiration, where NADH acts as an electron carrier, facilitating energy production.

Front

ATP needed to initiate glycolysis?

Back

2

Answer explanation

Glycolysis requires an initial investment of 2 ATP molecules to phosphorylate glucose and its intermediates, making 'Two' the correct answer.

Front

CO₂ is released during:

Back

Kreb's Cycle

Answer explanation

CO2 is released during the Kreb's Cycle, which occurs in the mitochondria. This process involves the oxidation of acetyl-CoA, resulting in the production of CO2 as a waste product, unlike glycolysis and the ETC.

Front

Location of glycolysis?

Back

Cytoplasm

Answer explanation

Glycolysis occurs in the cytoplasm of the cell, where glucose is broken down into pyruvate. This process does not take place in the mitochondria, which are involved in later stages of cellular respiration.

Front

Products of Krebs cycle

Back

ATP, NADH, FADH2, CO2

Answer explanation

The Krebs cycle produces ATP, NADH, FADH2, and carbon dioxide as key products. The correct choice includes all these products, highlighting the cycle's role in energy production and electron transport.

Front

Equation for cellular respiration:

Back

6O₂ + C₆H₁₂O₆ -> 6CO₂ + 6H₂O + Energy

Answer explanation

The correct equation for cellular respiration is 6O2 + C6H12O6 -> 6CO2 + 6H2O + Energy. This shows glucose and oxygen being converted into carbon dioxide, water, and energy, which is the process of cellular respiration.
