question 1/4

What is the purpose of cellular respiration?

Turn carbon dioxide from the air into sugar

Convert solar energy from the sun to chemical energy

Breakdown glucose to produce energy for the cell

Collect

question 2/4

Which choice lists the two types of cellular respiration?

aerobic & anaerobic

passive & active

light-dependent & light-independent

question 3/4

What organisms do anaerobic respiration and what do aerobic respiration?

Collect

aerobic - most eukaryotes and prokaryotes anaerobic - some prokaryotes (bacteria, archaea, fungi)

anaerobic - most eukaryotes and prokaryotes aerobic - some prokaryotes (bacteria, archaea, fungi)

question 4/4

How is cellular respiration a redox reaction?

Collect

because it directly produces oxygen from glucose

because it involves the transfer of electrons between molecules, where glucose is oxidized and oxygen is reduced

because it uses light energy to split water molecules

QUESTION 1/4

Which choice lists the products of glycolysis (per one glucose molecule) and where it occurs?

Milking

products - 2 pyruvate molecules, 2 ATP, 2 NADH location - occurs in the cytoplasm of the cell

products - 3 pyruvate molecules and 2 NADPH location - occurs in the nucleus of the cell

products - 1 glucose molecule and 4 ATP location - occurs in the mitochondria of the cell

QUESTION 2/4

Which choice lists the products of the intermediate step?

Milking

pyruvate, NADH, and FADH₂

Acetyl-CoA, NADH, and CO₂

glucose molecules and ATP

question 3/4

Which choice lists the products of the Krebs cycle (per one glucose molecule) and where it occurs?

Milking

products - 6 NADH, 2 FADH₂, 2 ATP, and 4 CO₂ location - occurs in the mitochondrial matrix

products - 2 NADH, 2 FADH₂, 2 ATP, and 2 CO₂ location - occurs in the nucleus

products - 4 NADH, 2 FADH₂, 6 ATP, and 2 CO₂ location - occurs in the cytoplasm

question 4/4

Where in the cell is the electron transport chain located?

Milking

it is located in the inner mitochondrial membrane

it is located in the cytoplasm

it is located in the nucleus

QUESTION 1/4

Where do electrons come from?

Feed

electrons come from glucose

electrons come from NADH and FADH₂

electrons come from oxygen

QUESTION 2/4

What happens in the intermembrane space as electrons go down the electron transport chain and what is its purpose?

Feed

protons (H⁺) are pumped from the matrix into the intermembrane space, creating an electrochemical gradient which is then used to make ATP in a process called chemiosmosis

the intermembrane space fills with oxygen, which is directly converted into water and used to create ATP without the proton gradient

protons are pumped into the nucleus, where they directly interact with DNA to produce ATP

QUESTION 3/4

How is water byproduct produced?

Feed

at the end of the ETC, electrons are transferred to oxygen (the final electron acceptor), and oxygen combines with protons (H⁺) to form water

water is produced during the citric acid cycle when glucose is converted into water along with ATP

during glycolysis, when glucose is broken down into pyruvate, water molecules are released as byproduct

QUESTION 4/4

What are the products of the electron transport chain (per one glucose molecule)?

Feed

glucose, oxygen, and FADH₂

6 H₂O (water) and 32-34 ATP

2 ATP, 2 NADH, and 6 CO₂

What are the products of lactic acid fermentation (per one glucose) and where does it occur?

question 1/4

Shearing

products - 2 lactate and 2 ATP location - occurs in the cytoplasm

products - oxygen and water location - occurs in the nucleus

products - glucose and carbon dioxide location - occurs in the mitochondria

Which of the following is an example of when lactic acid fermentation happens?

question 2/4

Shearing

it can happen in muscle cells during intense exercise when oxygen supply is insufficient for aerobic respiration

it happens in bacteria when they undergo aerobic respiration in the presence of oxygen

it happens in plants during photosynthesis when they produce glucose and oxygen

Which choice lists the final products of alcohol fermentation (per one glucose) and where it occurs?

question 3/4

Shearing

products - oxygen and water location - occurs in the mitochondria

products - lactic acid and 2 ATP location - occurs in the nucleus

products - 2 ethanol, 2 CO₂, 2 ATP location - occurs in the cytoplasm

Which of the following is an example of a use of alcohol fermentation?

question 4/4

Shearing

the conversion of glucose to lactic acid in muscle cells during intense exercise

the production of alcoholic beverages (such as beer or wine) by yeast, which ferments sugars to produce ethanol and carbon dioxide

the production of oxygen in plant cells during photosynthesis
