Lecture 6 Flashcards
What is anaerobic metabolism?
When there is an absence of oxygen glucose can be broken down by fermentation, which produces ATP
What is the process of fermentation?
Extracting energy from fuel molecules, and uses organic molecules as acceptor
What is metabolic integration?
Metabolic pathways are integrated which allows for the control of energy levels of cells
How much ATP is produced in each part of cell respiration
In glycolysis seven ATP is produced in pyruvate oxidation five ATP is produced in the citric acid cycle 20 ATP is produced giving a total of 32 ATP
What happens to oxidative phosphorylation when there is no oxygen
No no oxidative phosphorylation occurs meaning only four ATP is produced
What occurs in lactic acid fermentation? Is this from animals or plants?
Glucose is converted into pyruvate and electrons from NADH goes to pyruvate to form two lactic acids. This is from animals.
What occurs in ethanol fermentation and is this for plants or animals?
Peru release two CO2 and becomes acetaldehyde and electrons from NADH combine for two ethanol.
This occurs in plants
What is an efficient way of energy storage?
Glucose is stored as glycogen and starch
What does glycogen look like and where is it stored?
Ecogen has a protein, core surrounded by glucose branches and is stored in the muscle or liver cell cells
Main purpose of glycogen stored in muscle cells
They support muscle contraction
What is the main purpose of glycogen stored in liver cells?
It releases energy when needed
What happens when there’s a high level of ATP for ATP regulation
There’s a large amount of free energy and ATP regulation is stopped as there is too much ATP this also occurs with NADH
What happens in ATP regulation when the ATV levels are low?
The ATP synthesis pathways will open and the same thing will happen with NAD plus
