What stage of cellular respiration can occur in human cells with or without oxygen present?

What stage of cellular respiration can occur in human cells with or without oxygen present?

Glycolysis

How cells can harvest chemical energy with or without cellular respiration?

Fermentation provides a mechanism by which some cells can oxidize organic fuel and generate ATP without the use of oxygen or any electron transport chain (that is, without cellular respiration). o In glycolysis, glucose is oxidized to two pyruvate molecules with NAD+ as the oxidizing agent.

What are fats primarily broken down and converted into so that energy stored within these molecules can be harvested?

Chapter 7

Question Answer
What are fats primarily broken down and converted into so that energy stored within these molecules can be harvested? Acetyl-CoA
In glycolysis, glucose is converted to: pyruvate
The NET result of a single round of glycolysis is the formation of: 2 NADH and 2 ATP

What is the use of ATP give three examples of how ATP is used in the cell?

Food molecules are broken apart into smaller molecules in order to release ATP for cells to use. Give three examples of how ATP is used in organisms. ATP is used to build large molecules such as proteins, to temporarily store energy in the form of fat, and to allow for all types of cellular transport.

What are the three main kinds of cellular work?

Your cells perform three main types of work: chemical work, mechanical work, and transport work (Figure 7-10). An example of chemical work is building large molecules such as proteins. ATP provides the energy for the dehydration synthesis reaction that links amino acids together.

What is an example of transport work in a cell?

Transport Work-Pumping substances across membrane like sending ions across a plasma membrane. Sending substances such as protein around the cell is also a form or transport work.

Which is an example of chemical work in a cell?

An example of chemical work is building large molecules such as proteins. ATP provides the energy for the dehydration synthesis reaction that links amino acids together. An example of mechanical work is the contraction of a muscle. In your muscle cells, ATP transfers phosphate groups to certain proteins.

Which is an example of chemical work in a cell quizlet?

What is the best example of chemical work? Lactate dehydrogenase reduces pyruvate to form lactate. Skeletal muscle contraction pulls on tendons and moves bones. H+ will diffuse across the inner mitochondrial membrane to provide the energy that powers the ATP synthase enzyme.

Which is an example of transport work in a cell quizlet?

ATP transfers phosphate groups to certain proteins, causing protein to change shape and size. . An example of transport work is pumping solutes across a membrane. ATP transfers phosphate groups to membrane protein, causing protein to change shape and allow to pass.

Which of the following is the best example of feedback inhibition?

What is the best example of feedback inhibition? High ATP concentrations in the cell inhibit the action of phosphofructokinase, the third enzyme of glycolysis.

How is ATP renewed?

How is ATP renewed? Process by which energy comes from sunlight and food production (input) and drives the binding of ADP to a third phosphate group to produce ATP. Then water is added to ATP when energy is used to do work and perform any different cell processes to produce ADP.
