Which statement regarding regulation of the citric acid cycle is false? Ca2+ is involved in citric acid cycle regulation in vertebrate muscle. Dysfunction of the citric acid cycle (e. g., due to mutations in enzymes of the cycle) is often associated with different types of cancer. As [NADH]/[NAD+] increases, flux through the cycle increases. In addition to regulation of the PDH complex, regulation of the citric acid cycle occurs by regulation of the enzymes that catalyze the strongly exergonic steps.

Which statements are true concerning mineral formation? check all that apply. the slower the cooling, the larger the crystals. the faster the cooling, the smaller the crystals. crystals formed from magma are smaller than crystals formed from lava. minerals can only form in solutions when the solution is heated deep underground. when a solution cools, elements and compounds leave the solution and crystallize as minerals. minerals formed from hot water solutions can form narrow channels in the surrounding rock.
