Photosynthesis and glucose metabolism are related because:
the products of photosynthesis are used for glucose metabolism and vice versa
Where does fermentation occur?
cytoplasm
Where does glycolysis occur?
cytoplasm
Where does the Krebs cycle occur?
mitochondrial matrix
Glycolysis produces 2 molecules of _________, ________, and _________
ATP, NADH, and pyruvate
The NADH produced by glycolysis ultimately donates its high-energy electron to _________
oxygen
Cellular respiration is the process of:
producing ATP via the electron transport system
What is the final electron acceptor of the electron transport system?
oxygen
Cellular respiration occurs in the:
mitochondria
In prokaryotic cells, the Krebs cycle takes place in the:
cytoplasm
In prokaryotic cells, the electron transport system is located in the:
plasma membrane
Pyruvate produced by glycolysis is transported into the matrix, where:
it is split into CO2 and a 2-carbon acetyl group, which enters the Krebs cycle
Some of the energy that is lost in the electron transport system is used to:
pump hydrogen ions across a membrane
In chemiosmosis, hydrogen ions move from _________ to _________.
the intermembrane compartment
the matrix
The oxygen in the CO2 molecules produced in glucose metabolism comes from C6H12O6 during ___________
the Krebs cycle
Where is ATP produced?
cytoplasm and mitochondria
Glucose can be broken down into what two parts?
1. Glucose activation
2. Energy harvest
The production of _________ marks the end of glycolysis and the beginning of cellular respiration.
pyruvate
What does the electron transport chain do during cellular respiration?
Pumps hydrogen ions against their concentration gradient from the matrix to the intermembrane compartment
Reaction that breaks down glucose without the use of oxygen
glycolysis
Cellular respiration
series of reactions in which large amounts of ATP are produced
If oxygen is present after glycolysis, pyruvate is broken down further in:
the Krebs cycle
Electrons from NADH and FADH2 are deposited in the _____________.
electron transport system
In the absence of oxygen, pyruvate acts as the final electron acceptor from NADH, producing ethanol or lactate, in a process called ___________.
fermentation
Type of fermentation that occurs in muscles:
lactate
Products of the Krebs cycle:
6 NADH
2 FADH2
2 ATP
