Answer:
The answers are:
- Type 2 (fast twitch) muscle fibers - type A: b. muscle fibers that help with a long sprint or carry a heavy object a short distance
- muscular strength: d. the muscle's capacity to exert force against resistance
- Type 1 (slow twitch) muscle fibers: a. muscle fibers responsible for endurance
- Muscle endurance: c. refers to the ability to perform a specific muscular action for a prolonged amount of time.
- Type 2 (fast twitch) muscle fibers - type B: e. muscle fibers used in short explosive movements such as jumping or lifting a very heavy weight one or two times.
Explanation:
Types of Skeletal Muscles:
Skeletal muscle are divided into two types:
- Slow Twitch (Type 1)
- Fast Twitch (Type 2)
- Slow twitch muscles are the first ones to contract at times of exercise of strenuous physical activity. A compared to fast twitch muscle fibers, they contract slowly but can sustain contraction for a long time.
- Fast twitch muscle fibers are divided into two subtypes: Type 2A and Type 2B.
- Type 2A muscle fibers produce a high amount of force but they fatigue rapidly.
- Type 2B muscle fibers, fire last, produce the most amount of force but wear out very rapidly.
Muscle Characteristics:
- Muscle endurance is the muscle's ability to contract with force against a resistance for a prolonged time period.
- Muscle strength is a measure of the amount of force a muscle can produce against resistance.
ANSWER;
<u>FATS- a marathon; a 5-KM run; a soccer match,. an all day walkathon</u>
<u>Carbohydrate-a block start in 50-M freestyle</u>
;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.
