An activator of the enzymes present in the matrix regulating krebs cycle would
a) citrate
b) nadh
c) atp
d) succinyl coa
e) nad+

a) citrate

Explanation:

Aerobic respiration involves glycolysis and the tricarboxylic acid cycle (Krebs cycle). Pyruvate is completely degraded to carbon dioxide (CO2) and in the process, NAD is converted to NADH + H + The enzymes citrate synthase, isocitrate dehydrogenase and α-ketoglutarate dehydrogenase are the regulators of metabolic flow through the Krebs cycle and are subject to allosteric control involving NADH as inhibitor and Ca + and ADP as activators.

what subject is this

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
