During exercise, the body primarily relies on energy from carbohydrates, fat, adenosine triphosphate (atp), and creatine phosphate (cp) in varying combinations depending on the type of physical activity. consider the various activities below and sort them based on the primary energy source used during the activity. match the activity with the correct source of energy. sources of energy- atp-cp; carbohydrates, fata. activities- a marathon; b. a block start in 50-m freestyle; c. a 5-km run; a soccer match; d. an all day walkathon

ANSWER;

FATS- a marathon;  a 5-KM run; a soccer match,. an all day walkathon

Carbohydrate-a block start in 50-M freestyle

;Basically the longer   the C-H bonds in a food molecule, the larger the number of ATPs produced in aerobic respiration, from the number of C-H bonds broken and therefore the lager the quantity of ENERGY generated.

Simply put the more hydrogen atoms available, the more reduced co-enzymes NADH+ and FADH+ from kerb’s cycle to get oxidized for the Hydrogen atoms to be released in the matrix of the mitochondrial. The hydrogen atom is split to e-, and protons. The available protons is pump into the cytosol  around the double membrane of the mitochondrial by the energy generated from the electron chain set up  by the movement of e-  from one energy level protein carrier to another. The higher concentration gradients set up by the protons in the cytosols drive protons through the proton channels containing ATPase synthase into the matrix to generate ATPs.

Therefore strenuous exercises or long distance races like (marathon, a soccer match; a 5-KM run; and an all-day walkathon) (required larger supply of energy in form of ATPs from food substances of longer C-H bonds, and more hydrogen atoms. For example fats

the answer is otpion c) understanding

he wants to be heard one more time. he wants to be understood. he needs the truth one more time.

the "dirty dozen" chemicals banned in an international treaty are formally known as persistent organic pollutants, or pops. the united nations environment program provided this background on what they are and what they can do to humans and wildlife.

i hope this
