Choline acetyltransferase activity in the brain of goldfish acclimated to different temperatures
TLDR
The enzyme responsible for ACh synthesis, choline acetyltransferase, is stable at incubation temperatures higher than previous acclimation temperatures, and the activity of the enzyme is greater at higher acclimated temperatures.About:

Biochemical Adaptation to the Environment
TL;DR: It is proposed that adult poikilotherms may undergo a considerable degree of “biochemical restructuring” on a seasonal basis, and the factors which control this “restructuring,” and the rates at which the process occurs at high and low temperatures are topics for future investigation.
Journal ArticleDOI
Temperature acclimation and the nervous system.
TL;DR: The conduction velocity of the compound action potential of peripheral nerves shows compensatory acclimation to temperature in a fish, a snail, a crab, and probably also in the frog.
Journal ArticleDOI
The effect of temperature acclimation upon succinic dehydrogenase activity from the epaxial muscle of the common goldfish (Carassius auratus L.)--I. Properties of the enzyme and the effect of lipid extraction.
TL;DR: Results were interpreted as indicating that SDH normally functions as a lipoprotein complex within the inner mitochondrial membrane and exhibits properties which maintain temperature-independent catalytic function in response to short-term and prolonged temperature fluctuations.

Interpretation of inverse acclimation to temperature
Jeffrey Hazel,C. Ladd Prosser +1 more
TL;DR: In kidney of goldfish acclimated to 5, 15 and 25° C the peroxisomal enzyme peroxidase and the per oxisomal and cytoplasmic matrix enzyme catalase showed inverse (Precht type 5) acclimation.

2 - Biochemical Adaptation to the Environment
P.W. Hochachka,G.N. Somero +1 more
TL;DR: This chapter considers what progress has been made in the elaboration of control mechanisms involving modulator induced changes in enzyme-substrate (E-S) affinity and what avenues of future research seem most promising and relevant.

The assay and distribution of coenzyme A.
Nathan O. Kaplan,Fritz Lipmann +1 more
TL;DR: The results of assays for coenzyme A in various materials show a ubiquitous distribution of coen enzyme A in living cells.

The level of free choline in plasma
TL;DR: Previous assays of free choline in blood, plasma and serum are summarized, and shows a wide scatter of values ranging from l to 75,ug/ml, suggesting that such a wide range of values is unlikely.

Isoenzymes in metabolic adaptation of a poikilotherm: Subunit relationships in lactic dehydrogenases of goldfish
TL;DR: Electrophoretic evidence suggests the presence of tissuespecific isoenzymes of lactic dehydrogenase (LDH) in the goldfish, and the action of oxamate, an inhibitor competitive with pyruvate, is consistent with this interpretation.

Anaerobic and aerobic metabolism in gills of the crucian carp adapted to high and low temperatures
TL;DR: The activities of 6-phosphogluconic dehydrogenase and aldolase were greater in gills from cold-adapted fish than from warm- Adapted fish, and Catalase from gills of cold- and warm- adapteded fish was completely inhibited by 10 −3 cyanide.
Journal ArticleDOI
Changes in activity of cytochrome oxidase during adaptation of goldfish to different temperatures.
TL;DR: It is concluded that cold Acclimation causes an increase and warm acclimation a decrease in amount of cytochrome oxidase in goldfish muscle, also that in cold acclimations there is either an increase in a heat-sensitive inhibitor or a change which causes prolongation of thermal activation.
