How do cells harvest energy from glucose?

Question 1

How do facultative anaerobes act? What is their definition?

Answer 1

They are organisms that can grow with or without oxygen and they carry out either the anaerobic pathway or they obtain energy anaerobically

Question 1

How do organisms obtain energy from glucose?

Answer 1

using different metabolic pathways to obtain energy from glucose

Question 2

In what obligate anaerobes differ from facultative anaerobes?

Answer 2

They are harmed by oxygen and can only rely on anaerobic respiration to harvest energy from food

Question 3

How does the breakdown of glucose starts?(WORDS GLICOLYSIS)

Answer 3

It starts with glycolysis. An aerobic pathway consisting of 10 reactions that take place in the cytoplasm

Question 4

Explain shortly what happens during glycolysis

Answer 4

A molecule of glucose is converted into two pyruvate molecules, so that two molecules of ATP & NADH are released

Question 5

How does the process of complete breaking down of glucose is called?

Answer 5

Is called aerobic respiration. It occurs when oxygen is available

Question 6

What happens with oxidative phosphorylation?

Answer 6

A large amount of energy, in the form of ATP molecules, is produced.

Question 7

What happens if oxygen is not available? ANAEROBIC RENSPIRATION

Answer 7

Cells can obtain energy only from glycolysis, followed by fermentation.
