The correct formula for cellular respiration is:

Glucose + oxygen → carbon dioxide + water + ATP

This reaction indicates that glucose and oxygen are converted into carbon dioxide, water, and energy in the form of ATP.

Glycolysis is the first step in cellular respiration. Which option best summarizes the process?(1 point)
Responses

aerobic; 6-carbon glucose forms four 3-carbon ADP; forms a net total of 3 ATP
aerobic; 6-carbon glucose forms four 3-carbon ADP; forms a net total of 3 ATP

anaerobic; 6-carbon glucose forms two 3-carbon pyruvates; forms a net total of 2 ATP
anaerobic; 6-carbon glucose forms two 3-carbon pyruvates; forms a net total of 2 ATP

aerobic; 6-carbon glucose forms three 2-carbon pyruvates; forms a net total of 2 ATP
aerobic; 6-carbon glucose forms three 2-carbon pyruvates; forms a net total of 2 ATP

anaerobic; 6-carbon glucose forms two 3-carbon ADP; forms a net total of 4 ATP

The option that best summarizes the process of glycolysis is:

anaerobic; 6-carbon glucose forms two 3-carbon pyruvates; forms a net total of 2 ATP.

Glycolysis occurs in the cytoplasm and does not require oxygen, breaking down glucose into two pyruvate molecules and producing a net gain of 2 ATP.

The Krebs cycle forms many products. Which option lists the correct products of the Krebs cycle after 1 molecule of glucose goes through it?(1 point)
Responses

net 4 NADH, 4 ATP, 8 CO2, 4 FADH2
net 4 N A D H , 4 A T P , 8 C O sub 2 , 4 F A D H sub 2

net 2 NAD+, 2 ATP, 4 CO2, 2 FADH
net 2 N A D plus , 2 A T P , 4 C O sub 2 , 2 F A D H

net 1 NADH, 1 ATP, 2 CO2, 1 FADH2
net 1 N A D H , 1 A T P , 2 C O sub 2 , 1 F A D H sub 2

6 NADH, 2 ATP, 4 CO2, and 2 FADH2

The correct option that lists the products of the Krebs cycle after 1 molecule of glucose goes through it is:

6 NADH, 2 ATP, 4 CO2, and 2 FADH2.

For each molecule of glucose, which produces two acetyl CoA molecules that enter the Krebs cycle, the cycle will produce this amount of products.

Why are NADH and FADH2 necessities in the electron transport chain?(1 point)
Responses

They move down the electron transport chain.
They move down the electron transport chain.

They move electrons to the electron transport chain.
They move electrons to the electron transport chain.

They remove electrons from the electron transport chain.
They remove electrons from the electron transport chain.

They accept electrons in order to power the electron transport chain.
They accept electrons in order to power the electron transport chain.

The correct response is:

They move electrons to the electron transport chain.

NADH and FADH2 are essential because they carrier molecules that transport high-energy electrons from the Krebs cycle to the electron transport chain, where their energy is used to produce ATP.
