Aerobic Cellular Respiration Test Study Guide

What is the chemical reaction for cellular respiration?

C6H12O6 + 6O2 --> 6CO2 + 6H2O + ATP

How many ATP are made in cellular respiration?

2

Describe the energy transformation that takes place in cellular respiration?

Chemical energy from glucose is. turned into cellular energy also known as ATP.

How is the equation similar and how is it different to the equation for photosynthesis?

Cellular respiration and photosynthesis have products and reactants in inverse order.

What is the purpose of cellular respiration?

We need it to generate energy for cells.

What are the three steps to aerobic cellular respiration?

Glycolysis, krebs cycle, and the electron transport chain.

What molecule is needed, that is made in photosynthesis to start cellular respiration?

Glucose.

What molecule needs to be present in order for aerobic respiration to occur?

Oxygen.

If oxygen is not present what type of respiration would it be?

Anaerobic respiration.

What are the two types of fermentation that would happen if you did anaerobic respiration and how are they different?

Lactic acid - waste product that causes muscle soreness. Alcoholic - pyruvate from glycolysis is converted to ethanol and carbon dioxide.

What is the purpose of glycolysis?

To break down sygar from pyruvate to generate energy.

What is the purpose of the krebs cycle?

To produce ATP.

What is the purpose of ETC?

To produce electrons that produce ATP synthase.

Where does glycolysis happen?

Cytoplasm.

Where does the krebs cycle happen?

Matrix.

Where does the ETC happen?

Cristae.

What are the reactants of glycolysis?

Glucose

What are the reactants of krebs cycle?

NAD+, FAD, GDP

What are the reactants of ETC?

NADH, FADH, O2

What are the products of glycolysis?

Pyruvate, 2ATP, 2NADH

What are the products of krebs cycle?

CO2, NADH, FADH2, GTP

What are the products of ETC?

ATP, H2O

Briefly describe what happens in glycolysis?

Glucose is broken into 2 pyruvate generating 2 ATP molecules.

Briefly describe what happens in krebs cycle?

Molecule is oxidized to produce energy while releasing CO2 as a byproduct.

Briefly describe what happens in oxidative phosphorylation?

Electrons are carried from molecules reaching oxygen used to later create ATP synthase.

What molecule accepts all electrons at the end of the ETC?

Oxygen.

What are the two byproducts of respiration?

CO2 and H2O

What are the two electron carries used in respiration?

NAD+ and FAD

What happens to NADH and FADH once they finish doing their job in the ETC?

They turn back into NAD+ and FAD to go through the process again.
