Substrate phosphorylation - Study guides, Revision notes & Summaries

it is true that a eukaryotic cell. contains structures called organelles Eukaryotic cells contain organelles and histones, they have a well-defined nucleus, and are larger than prokaryotic cells. The function of a histone found in a eukaryotic cell focuses on cellular deoxyribonucleic acid (DNA) folding The histones are binding proteins that cause the supercoiling of DNA into chromosomes and do not affect cellular division, movement, or activities. An organelle that is responsible for th...

Bioengernetics - Answer-How energy flows through organisms. ATP - Answer-Used for mechanical, transport, and chemical work. ATP is also an RNA nucleotide. Mechanical Work - Answer-Energy used in motor proteins and muscle cells during contractions. Transport Work - Answer-Energy used to move substances against their gradient. Chemical Work - Answer-Energy used to convey polymers into monomers. Gibs Free Energy - Answer-Portion of a systems energy that can preform work when temperature and p...

2 ways phosphate addition/removal causes conformational changes - Answer 1)Phosphorylation has a lot of negative charges that interfere with interactions between substrates --> forces protein into different conformations 2) phosphorylation of an enzyme can also alter substrate-binding affinity via electrostatic repulsion what happens to the GPCR and g-protein when a hormone reaches the GPCR receptor on cell membrane? - Answer hormone triggers a conformational change in receptor, which s...

MCAT Bio/Biochem Questions and Answers | Latest Version | 2024/2025 | 100% Verified Explain the role of the sodium-potassium pump in maintaining resting membrane potential. The sodium-potassium pump actively transports three sodium ions out of the cell and two potassium ions into the cell, helping to maintain the resting membrane potential by creating an electrochemical gradient. Describe the process of oxidative phosphorylation in cellular respiration. Oxidative phosphorylatio...

AP BIOLOGY UNIT 2 TEST QUESTIONS WITH VERIFIED ANSWERS Compare and contrast P2 and P1. Photosystem II begins , which absorbs wavelengths at a wavelength of 680 nm. Here, energy is absorbed and passed along until it reaches P680 chlorophyll. When this chlorophyll is excited, it sends its electrons to the primary electron acceptor. Electrons are taken from H2O and passed to P680 to replace the electrons given to the primary acceptor. This forces O2 to form. The electrons are passed to ph...
