Select the correct formula for cellular respiration.(1 point)
Carbon dioxide + glucose → oxygen + water + ATP
Carbon dioxide + water + ATP → glucose + oxygen
Glucose + water → oxygen + carbon dioxide + ATP
Glucose + oxygen → carbon dioxide + water + ATP
Glycolysis is an anaerobic process in which a 6-carbon glucose molecule is broken down into two 3-carbon pyruvate molecules. It forms a net total of 2 ATP. Therefore, the correct option is:
anaerobic; 6-carbon glucose forms two 3-carbon pyruvates; forms a net total of 2 ATP
Glucose + oxygen → carbon dioxide + water + ATP
In what organelle do the Kreb’s cycle and the electron transport chain take place?
(1 point)
mitochondria
nucleus
chloroplast
cytoplasm
The Krebs cycle and the electron transport chain take place in the mitochondria.
The correct products of the Krebs cycle after 1 molecule of glucose goes through it are:
6 NADH, 2 ATP, 4 CO2, and 2 FADH2
Why are NADH and FADH2 necessities in the electron transport chain?(1 point)
They accept electrons in order to power the electron transport chain.
They move electrons to the electron transport chain.
They move down the electron transport chain.
They remove electrons from the electron transport chain.
NADH and FADH2 are necessities in the electron transport chain because they donate electrons to the chain.
The correct formula for cellular respiration is: Glucose + oxygen → carbon dioxide + water + ATP.
To understand why this is the correct formula, let's break it down:
1. Glucose is a simple sugar molecule that serves as the main source of energy in cellular respiration.
2. Oxygen is necessary for the process of cellular respiration because it acts as the final electron acceptor in the electron transport chain.
3. During cellular respiration, glucose molecules are broken down, releasing energy in the form of ATP (adenosine triphosphate). ATP is the energy currency of the cell and is used to power various cellular processes.
4. As a result of breaking down glucose, carbon dioxide and water are produced as waste products.
5. Carbon dioxide is released as a byproduct when glucose is oxidized during cellular respiration.
6. Water is formed as a result of the combination of electrons and hydrogen atoms from glucose with oxygen.
So, the correct formula for cellular respiration is Glucose + oxygen → carbon dioxide + water + ATP.
