[q json=”true” question_number=”1″ xx=”2″ dataset_id=”cellular-respiration-click-on-challenge|2cc72646f3558″ hotspot_user_interaction=”label_prompt”] Structure of ATP
Phosphate groups
Excellent. The phosphate groups are at number 3.
HINT FOR NEXT TIME: What letter does “Phosphate” begin with.
Ribose
Nice job. Number “1” is the 5-carbon sugar ribose.
HINT FOR NEXT TIME: Ribose is a monosaccharide with five carbon atoms.
Adenine
Nice! “2” is adenine
HINT FOR NEXT TIME: Adenine is a nitrogenous base. Look for nitrogen.
HINT FOR NEXT TIME: ATP has three phosphates attached to the ribose sugar.
ADP
Way to go! That’s ADP.
HINT FOR NEXT TIME: ADP stands for adenosine diphosphate. Diphosphate means “two phosphate groups.”
Energy for transforming ADP + P into ATP
Fabulous. “A” represents energy for transforming ADP + P into ATP
No. Which arrow could represent energy for combining ADP and P into ATP?
Energy for cellular work
Way to go. B represents energy available for cellular work.
HINT FOR NEXT TIME: When ATP (with three phosphates) becomes ADP, energy becomes available for work. What arrow shows ATP becoming ADP.
Inorganic phosphate
Excellent!
No. Look for a phosphate group that’s not attached to a sugar and a base.
[q json=”true” xx=”2″ dataset_id=”cellular-respiration-click-on-challenge|723fc5d0beb3d” question_number=”3″ hotspot_user_interaction=”label_prompt”] Name the Four Phases of Respiration
Glycolysis (Click the number)
Nice! Number “1” represents glycolysis.
HINT FOR NEXT TIME: Glycolysis starts with glucose, and breaks it into two 3-carbon molecules.
The Link Reaction (Click the number)
Awesome. Number 2 represents the link reaction.
HINT FOR NEXT TIME: The link reaction brings pyruvic acid across the mitochondrial membranes. It links Glycolysis with the Krebs Cycle.
The Krebs Cycle (Click the number)
Magnificent! Number “3” represents the Krebs cycle.
HINT FOR NEXT TIME: It’s a cycle!
Oxidative phosporylation
(Click the number)
Way to go. Number 4 represents oxidative phosphorylation.
HINT FOR NEXT TIME: This process requires oxygen (so look for O2) .
Excellent. Proton pumps are represented by number 3.
HINT FOR NEXT TIME: Find arrows that move protons (H+) from low to high concentration.
ATP synthase channel.
Great! ATP synthase is represented by number 5.
HINT FOR NEXT TIME: ATP synthase is a channel that lets protons diffuse through.
Area with lowest pH
Good work. The intermembrane space has the lowest pH
HINT FOR NEXT TIME: Find an area with a lot of protons.
Reduced molecules that power the ETC.
Nice job. NADH and FADH2 are the reduced molecules that power the ETC.
HINT FOR NEXT TIME: Look for the molecules that donate electrons to the electron transport chain (ETC).
[q json=”true” xx=”2″ dataset_id=”cellular-respiration-click-on-challenge|70c0546a81f3d” question_number=”9″ hotspot_user_interaction=”label_prompt”] Where cellular respiration happens
Where glycolysis happens
Nice. Glycolysis happens in the cytoplasm (region 3)
HINT FOR NEXT TIME: Glycolysis happens in the cytoplasm.
Where the Krebs cycle happens.
Great! Krebs happens in the matrix (at 5)
HINT FOR NEXT TIME: Krebs happens in the mitochondrial matrix, which is like the cytoplasm of the mitochondrion.
Where protons get pumped to.
Awesome. Protons get pumped to the intermembrane space (at 7).
HINT FOR NEXT TIME: Protons get pumped to the intermembrane space.
[q json=”true” xx=”2″ dataset_id=”cellular-respiration-click-on-challenge|703685eabb33d” question_number=”10″ hotspot_user_interaction=”label_prompt”] The Four Phases: Key Molecules
Acetyl-CoA
Nice. Acetyl-CoA is represented by “E.”
HINT FOR NEXT TIME: <span style=”font-size: 13.3333px;”> Acetyl-CoA comes out of the link reaction and goes into the Krebs cycle. </span style=”font-size: 13.3333px;”>
Pyruvic acid (pyruvate)
Nice! Molecule “D” is pyruvic acid (pyruvate)
HINT FOR NEXT TIME: Look for a 3-carbon molecule that comes out of glycolysis and goes into the link reaction.
Glucose
Nice. Molecule “A” is glucose.
HINT FOR NEXT TIME: Look at the start of glycolysis.
