Activation energy is the minimum quantity of energy that the reacting species must possess in order to undergo a specified reaction.
for example , striking a match on the side of a matchbox provides the activation energy, in the form of heat produced by friction.
Answer:
Your digestive system absorbs water and nutrients from the food you eat. Your circulatory system carries oxygen, water, and nutrients to cells throughout your body. Wastes from the cells are eliminated by your respiratory system, your excretory system, and your skin.
Explanation:
Answer: The ATP(Adenosine Triphosphate) that will be generated if one pyruvate molecule is carried through cellular respiration is 36.
Explanation: Pyruvate is formed through glycolysis cycle which breaks down glucose. The pyruvate is used in aerobic cellular respiration via the TCA cycle yielding 2 ATPs and the electron transport system yielding 34 ATPs. That makes it up to a total of 36 ATPs.
Answer:
well I dnt know
btw thanks for ur points I really needed that.
Answer: These contractions need energy from respiration , and some of this is released as heat. Blood vessels, which lead to the skin capillaries, become narrower - they constrict – which allows less blood to flow through the skin and conserve the core body temperature. This is called vasoconstriction.
