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

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

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
