Fill in the Blank

A person suffering a heart attack is not receiving adequate Oxygen to the heart muscle. What type of muscle is the heart muscle?

Multiple Choice

The Small intestine and the Large intestine are great examples of a _____ muscle, and the type of contraction is termed _____

• skeletal, musculoskeletal

• smooth, peristalsis

• cardiac, excitation contraction coupling

Multiple Select

Check all that apply. Muscle types that are striated

• skeletal

• cardiac

• smooth

• visceral

Types of muscle tissues

• skeletal-striated-voluntary movement

• cardiac-striated-involuntary heart contractions

• smooth- non-striated- involuntary peristalsis contractions

Multiple Choice

What part of this structure anchors the thin filament? # 1

• Sarcomere

• thin filament

• thick filament

• z disc

• titin filament

Multiple Choice

What part of this structure is myosin #3

• Sarcomere

• thin filament

• thick filament

• z disc

• titin filament

Multiple Choice

What is the functional unit of a muscle cell? #7

• Sarcomere

• thin filament

• thick filament

• z disc

• titin filament

Functional unit of the muscle

• # 7 sarcomere

• #1 and #6 z disc- anchors the thin filament

• #2 thin filament- contains actin

• #3 Thick filament- myosin and myosin heads

• # 4 the m line

• # 5 titan filament- coiled helps anchor myosin and allows for the sliding effect

Multiple Choice

Which stage of the cellular respiration process produces the most ATP?

• Glycolysis

• Acetyl CoA

• Kreb's Cycle

• Electron Transport Chain

Multiple Choice

What is cellular respiration?

• the breakdown of glucose  to release ATP
• the breakdown of glucose to release NADH
• the breakdown of glucose to release FADH
• the breakdown of glucose to release carbon

Multiple Select

A person suffering a heart attack is not receiving adequate Oxygen to the heart muscle. When a muscle cells lacks oxygen, it undergoes (check all that apply)

• aerobic respiration

• anaerobic respiration

• glycolysis

• Krebs

• ETC

Cellular respiration review

• Glycolysis-anaerobic respiration

• intermediate rxn- pyruvate to Acetyl CoA

• Krebs cycle

• ETC-electron transport chain (majority of ATP formation)

Multiple Choice

The neuron innervates a muscle cell by releasing Ach (acetylcholine) into the synapse resulting in an intracellular increase of ____ ion

• Ca

• Na

• P

• ATP

Multiple Choice

the conformational change of inactive actin to active form results in the myosin heads to attach forming

• crossbridge

• ATP

• contraction

• influx of Ca

Fill in the Blank

The final step of the contraction of a muscle is when the myosin head pulls on the actin resulting

Multiple Choice

Oxygen debt definition:

• the failure to meet the body's oxygen demand

• the volume of oxygen used during recovery from exercise that is higher than resting oxygen consumption

• the cool down phase of exercise

• when oxygen demand = supply

Multiple Choice

What is the definition of oxygen debt?

• Amount of oxygen used for aerobic activity minus amount of oxygen actually used

• Amount of oxygen needed at the end of a physical activity to break down any lactic acid

Multiple Choice

Insufficient O₂ leads to _____ resulting in the need to continue deeply breathing post exercise

• Oxygen debt and EPOC

• Oxygen debt and muscle fatigue

• Muscle fatigue and EPOC

Fill in the Blank

A person suffering a heart attack is not receiving adequate Oxygen to the heart muscle. lack of oxygen results in a lack of

O₂ Debt

• When there is a deficit of available oxygen to produce ATP

• anaerobic respiration-and lactic acid build up

• EPOC- requires deep breathing post exercise to breakdown latic acid

Multiple Choice

When a muscle lack sufficient ATP to contract due to extended O₂ or Ach (acetylcholine) deficiency

• muscle fatigue

• O₂ debt

• EPOC

Muscle fatigue

• prolonged and intense muscle use

• lack of ATP

• resulting in temporary loss of function
