According to the summary of aerobic respiration, protons are moved from the matrix of mitochondria to the intermembrane space. What is the significance of this step? How do protons return to the matrix? What’s the significance of this step?
Answer:
Movement of protons from the matrix of mitochondria to the intermembrane space assist to transfer of electrons from one carrier to the other and finally to reach to the oxygen and becomes water. It also creates proton imbalance accross the membrane.
Movement of protons from the intermembrane space to matrix through ATP synthase releases energy, which helps in the synthesis of ATP from ADP & ip.

Draw a mitochondria and label the outer membrane, inner membrane, intermembrane space, and matrix. Label on your drawing the names of the 3 steps of aerobic respiration and where each of them take place.
1- In animal mitochondria, H+ protons are actively pumped from ___ to ____. a. the cytosol; the intermembrane space b. the matrix; the intermembrane space c. the matrix; the cytosol d. the intermembrane space; the cytosol e. the intermembrane space; the matrix 2- Which of the following characteristics of the human mitochondrial genome is FALSE? a. Circular form b. Inherited primarily from mother c. Encodes all necessary proteins the mitochondria needs, including enzymes for transcription and translation d. Genetically similar...
Question 37 (1 point) In cellular respiration, electrons are moved along a series of membrane proteins during the electron transport chain. If there was a mutation in the DNA coding for each of the proton pumps of the electron transport chain such that these proteins became non-functional, what would you predict to occur? NADH and FADH2 would have to donate their electrons directly to ATP synthase in order for ATP synthesis to occur. All electrons would have to be stripped...
5. What are the internal structures of the mitochondria and what parts of cellular respiration take place in each part? (inner/outer membranes, cristae, matrix, intermembrane space)
In the mitochondrion, where does the electron transport chain pump protons? a. from the matrix to the intermembrane space b. from the intermembrane space to the matrix c. from the cytosol to the intermembrane space d. from the intermembrane space to the cytosol e. from the cytosol to the matrix through membrane contact sites
In mitochondria, the electron transport chain pumps H+ ions from the matrix into the intermembrane space. In chloroplasts, the electron transport chain pumps H+ ions from the thylakoid space into the stroma o outside the chloroplast into the stroma the chloroplast outer membrane into the intermembrane space the stroma into the matrix
In mitochondria, a proton gradient is established by the movement of electrons through the electron transport chain. Protons are moved to the intermembrane space against the concentration gradient and the flow back to the matrix via facilitated diffusion using the ATP synthase. Describe how this proton flow contributes to ATP synthesis and the role played by aspartic acid in this process.

Cellular Metabolism Lab We will walk through the steps of Cellular Respiration in this activity. Please do not skip ahead or leave out steps. Fully taking the time to cut out, arrange the shapes, and answer the attached questions will help you to gain a deeper understanding of cellular respiration (the process of making energy, ATP, the major contributor to our overall metabolism). Pages 941-948 in you TEXTBOOK should help you answer the questions. Grading Notes: You can either 1)...
Ch. 9 11) What are the four steps of cellular respiration? What are the initial reactants and final products from each of these steps (include NADH and FADH2)? Where do they occur in the cell/mitochondria? 12) Why is the pyruvate processing step necessary? Why not go straight to the citric acid cycle? 13) What is homeostasis? How does cellular respiration play a role in anabolic reactions (think intermediates)? 14) How are the first three steps of cellular respiration regulated? 15)...
