Proton gradient - Study guides, Class notes & Summaries

Protons are pumped by mitochondria during active electron transport correct answers outside the inner mitochondrial membrane. As electrons from NADH pass through the electron transport system, correct answers protons are pumped across the mitochondrial membrane to create a pH gradient. The first enzyme in the electron transport system is referred to as complex I, otherwise known as correct answers NADH-ubiquinone oxidoreductase. Which statement is true of the mitochondrial electron tran...

NUSCTX 10 Midterm 1 - UC Berkeley Latest Update Already Graded A Anabolism Uses energy to construct components of cells. Catabolism Breaks down organic matter, for example, to harvest energy. Nutrient Density A measure of the nutrient a food provides compared to its energy content. Trace Minerals Needed only in tiny amounts. These minerals participate in most chemical reactions in the body. These include iron, zinc, iodine, copper, manganese. Protein Complementation The act...

ARMRIT Exam Questions With 100% Correct Answers | Updated & Verified 2024/2025. The NMV is rotated to the physical negative Z axis by applying a...? - C)180 pulse Increasing which parameter is considered the "best" technique for improving image quality? - C)NEX Studies have concluded that static magnetic fields up to what tesla produce no substantial harmful biological effects. - C)2.0 Tissues that have low (short) relaxation times have: - Higher relaxation rates Nuclei in their natural e...

Cytochrome c oxidase correct answers An enzyme responsible for electron transfer in the ETC, so inhibiting it would slow or stop the ETC. Dosing of Blast Phase Chronic Myeloid Leukemia (BP-CML) cells with cyanide would result in: correct answers Reduced intercellular ATP and apoptosis or necrosis. Cyanide binds to cytochrome c oxidase and prevents electron transfer. Inhibiting cytochrome C oxidase would decrease ATP production. thus, large dose would also cause cell death (apoptosis or ne...
